However, the only meaningful thing I do in this case is - spawn another process with Bug Reporting GUI and try to create a current process dump. If the OS is catching it and killing the process, there is not much you can do (but prevent access violation by checking your boundaries and memcpy) share|improve this answer answered Quote: int get_bar(void) { if(bar != NULL) return bar; else return NULL; } This is not different to just return bar;. I would give you more for output, but I can't figure out how to get a call stack at the moment and I gotta leave for work in a minute (to http://stackoverflow.com/questions/30806174/catch-the-access-violation-reading-location-0x00000000-exception

  • Implementation defined means that the implementation must specify what takes place.
  • Yep.
  • In looking at your disassembly code example, while I cannot conclusively confirm this, it appears that mecej4 may be onto something where you are calling a function who's interface was not

Unhandled Exception Access Violation Reading Location Visual Studio I will try Inspector on Monday, then I will share the results. If you use new you must use delete, and if you use malloc you must use free. Since I never set17 * a or b to an address do I need to call free()?

Note that it is fine to return NULL; the problem is when you try to access the memory at location NULL. Access Violation Reading Location 0xc0000005 Why leave magical runes exposed? How do you define sequences that converge to infinity? Your solution is to make sure that Caller() does not return garbage.

There are a few C routines, but none of them are called.  My first reaction to this error was to compile/link without the C objs and comment out the calls to Exception Thrown: Read Access Violation.
