Виндовс у меня 10.
Раньше все шло нормально, но потом удалил игру, скачал сейчас обратно, установил САМП и тут такая ошибка. Как ее исправить?

I have been struggling with this for a while and was wondering if anyone could help. I am trying to make a particle sample using C++ and SDL1.3 and I have had great success up until this point. The program compiles and the screen opens and nothing happens. When I run the debugger I get this error:

Unhandled exception at 0x0102414a in SDL 1.3 Space.exe: 0xC0000005: Access violation reading location 0x00000008. The program ‘[7272] SDL 1.3 Space.exe: Native’ has exited with code -1073741819 (0xc0000005).

and it points to this piece of the code:

It would be greatly appreciated if someone would be so kind as to help me and /or point me in the right direction.

I’m having a very strange issue with a space invaders game I’m working on. Basically I get an access violation error:

Unhandled exception at 0x5edad442 (msvcr100d.dll) in SpaceInvaders.exe: 0xC0000005: Access violation reading location 0x00000000.

when I include the piece of code below. visual studio takes me to "strcmp.asm" when debugging. Note that Im not using strcmp() in any of my code. Is there anything wrong with the code, or is this a problem beyond the scope of what I’ve included? Thanks for any help

This line looks suspicious:

You’re never incrementing i , so you keep assigning to invaders[0] . If this is just an error you made when reducing your code to the example, check how you calculate i in the real code; you could be exceeding the size of invaders .

If as your comment suggests, you’re creating 55 invaders , then check that invaders has been initialised correctly to handle this number.

"Access violation reading location 0x00000000" means that you’re derefrencing a pointer that hasn’t been initialized and therefore has garbage values. Those garbage values could be anything, but usually it happens to be 0 and so you try to read from the memory address 0x0 , which the operating system detects and prevents you from doing.

Check and make sure that the array invaders[] is what you think it should be.

Also, you don’t seem to be updating i ever — meaning that you keep placing the same Invader object into location 0 of invaders[] at every loop iteration.

The problem here, as explained in other comments, is that the pointer is being dereference without being properly initialized. Operating systems like Linux keep the lowest addresses (eg first 32MB: 0x00_0000 -0x200_0000) out of the virtual address space of a process. This is done because dereferencing zeroed non-initialized pointers is a common mistake, like in this case. So when this type of mistake happens, instead of actually reading a random variable that happens to be at address 0x0 (but not the memory address the pointer would be intended for if initialized properly), the pointer would be reading from a memory address outside of the process’s virtual address space. This causes a page fault, which results in a segmentation fault, and a signal is sent to the process to kill it. That’s why you are getting the access violation error.
