I use Linux Mint 18.3. Recently I downloaded a game for Windows called SCP Containment Breach. I have managed to get it to run, but it crashes shortly afterwards during the loading screen and a small window pops up saying 'Memory access violation'.

Computer programs access system memory for processing. Humans draw upon our own stored memory to perform daily tasks. When a computer program tries to access a piece of memory that doesn't exist or otherwise access memory the wrong way (we'll cover this later), it will crash.

Consider the following scenario: a memory access violation, also called a segmentation fault (or segfault), occurs when the program tries to access a memory location that doesn't exist or is otherwise inaccessible. We call this trying to access an illegal memory location. The memory is either non-existent or we aren't allowed to touch it.

The segmentation fault will happen if one of the variable types listed tries to access memory outside of the segment where it lives. It can also happen if a segment is set to read-only. We've all had that happen in our daily lives; trying to copy or save files and they are read-only. It's the same concept, only the memory is read-only, and the program can't make the update to the variable.

One of the most common examples of memory errors occurs with arrays. An array is a single variable that can hold multiple buckets. Think of a baseball team's starting roster. It will have nine buckets. Once you set up the array in your program, there will be consequences if you try to write or access the tenth bucket. Remember, programs start counting at zero. Our first batter is batter 0, the ninth is batter 8.

Pointers, which are variables that hold a memory location instead of a value, can cause memory access violations. Languages like C and C++ allow the use of pointers. A function, such as scanf(), could be misused and try to point to a memory location that doesn't exist or is read-only.

Sometimes errors occur because the system memory isn't up to par (for example, running a massive game on an ancient Windows machine). However, many programming tools have options for catching these errors. Debuggers can be used to help you find potential errors. Languages such as Java provide syntax for trapping potential errors and not crashing the program (called try and catch statements). Another good practice is the old-fashion desk-check. Step through each line of code carefully on paper. Sometimes we miss things that are obvious when on the computer screen.

All right, let's now take a moment or two to review. As we learned, memory access violations occur when a program tries to update or access a memory address that doesn't exist (or is otherwise inaccessible). Memory is divided into segments that include the following:

Basically, when a variable tries to access or update memory outside of its segment, memory access violations occur. A common access violation happens with arrays (i.e., trying to update an array bucket that doesn't exist). Pointers, which are variables that store memory addresses, can also cause errors as they can easily wind up pointing to addresses that don't exist. Debuggers, syntax (such as Java's try and catch), and manual code walkthroughs can help prevent these errors.

Data Execution Prevention (DEP) is a system-level memory protection feature that is built into the operating system starting with Windows XP and Windows Server 2003. DEP enables the system to mark one or more pages of memory as non-executable. Marking memory regions as non-executable means that code cannot be run from that region of memory, which makes it harder for the exploitation of buffer overruns.

DEP prevents code from being run from data pages such as the default heap, stacks, and memory pools. If an application attempts to run code from a data page that is protected, a memory access violation exception occurs, and if the exception is not handled, the calling process is terminated.

If an application attempts to run code from a protected page, the application receives an exception with the status code STATUS_ACCESS_VIOLATION. If your application must run code from a memory page, it must allocate and set the proper virtual memory protection attributes. The allocated memory must be marked PAGE_EXECUTE, PAGE_EXECUTE_READ, PAGE_EXECUTE_READWRITE, or PAGE_EXECUTE_WRITECOPY when allocating memory. Heap allocations made by calling the malloc and HeapAlloc functions are non-executable.

An application can use the VirtualAlloc function to allocate executable memory with the appropriate memory protection options. It is suggested that an application set, at a minimum, the PAGE_EXECUTE memory protection option. After the executable code is generated, it is recommended that the application set memory protections to disallow write access to the allocated memory. Applications can disallow write access to allocated memory by using the VirtualProtect function. Disallowing write access ensures maximum protection for executable regions of process address space. You should attempt to create applications that use the smallest executable address space possible, which minimizes the amount of memory that is exposed to memory exploitation.

You should also attempt to control the layout of your application's virtual memory and create executable regions. These executable regions should be located in a lower memory space than non-executable regions. By locating executable regions below non-executable regions, you can help prevent a buffer overflow from overflowing into the executable area of memory.

A small number of executable files and libraries may contain executable code in the data section of an image file. In some cases, applications may place small segments of code (commonly referred to as thunks) in the data sections. However, DEP marks sections of the image file that is loaded in memory as non-executable unless the section has the executable attribute applied.

Since I don't know much coding, I just wanted to do it for help.because 90% of new modders get this memory access violation error while compiling the mod, so I wanted to do something like this. I think it's a great article for those who are just starting out with mods :D

When memory access violation problems occur, you commonly receive a prompt to run the memory diagnostics tool. However, this is not always the case. Symptoms of memory problems include slow-running computers, or delayed or stopped response after clicking on a button. A blank area where a multimedia graphic should appear is another symptom that there is not enough memory to display the contents on the screen.

"·F 0:00:52.098577 {PPU[0x1000000] Thread (main_thread) [0x004901cc]} VM: Access violation reading location 0x0 (unmapped memory)" when this occurs. After doing some research, the method for solving similar issues appeared to be enabling libraries, though none of the ones specified in such cases worked.

An access violation occurs in unmanaged or unsafe code when the code attempts to read or write to memory that has not been allocated, or to which it does not have access. This usually occurs because a pointer has a bad value. Not all reads or writes through bad pointers lead to access violations, so an access violation usually indicates that several reads or writes have occurred through bad pointers, and that memory might be corrupted.

An access violation often comes when we try to access or delete already-freed memory. The trick is ; when you know the memory address where the access violation occurs your can create a data breakpoint and wait until it get triggered. After that it will reveal you where and when this memory has been freed or modified.

When the DMV sys.dm_os_memory_objectsis used in a batch-mode query that executes inparallel, a race condition might occur that results in an access violation inSQL Server. Status Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

memory access violation is a NX message, if it is temporary, i.e not an error that is saved in the Partfile, it will disappear if you close /reopen the part, or if it is the running NX software that has become corrupted, a restart of NX will replace the running code with fresh.

This process is related to the Automatic Updates service. This access violation occurs when you use Automatic Updates to scan for updates by using the daily automatic schedule or when you visit the Microsoft Update Web site to manually scan for updates. A memory leak occurs when Windows Update scans for updates that use Windows Installer.

An access violation is a non-specific error that occurs while installing, loading, or playing a game. This error can be caused by the following: an interfering software program (usually an antivirus application), an outdated video card driver, or an outdated version of DirectX.

Dialog memory file becomes bigger as you using more and more features and from time to time it becomes too big. It could possibly lead to some NX errors, such as memory access violation. In that case you have to delete it. To locate the file you need to find the Unigraphics Solutions folder.

Nx memory access violation is known as an instance of the unnumbered blue screens. That will not be lost minutes you expend on a search for a remedy, the error requires to be removed at the earliest possible time.
