That will bring you down. Emreka82, Please try to try to follow steps 4, 5 and 6. 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. Does it make sense? this contact form

This way you will find the point in your code where it goes wrong and can step the program line by line. Just enable /EHa option in the project settings.

No, it should not. We can go on and give many more examples, but they may not help you. As it stands I am not even sure where the error is coming from as when I use the debugger all the variables seem to be in order and there is

Again, a handle rather than a pointer will solve this. On a rolodex card, you might use a '?', or a blank sheet - with pointers, we use the value NULL.Now for the allocation. So, there should not be any limitations for Stack/Heap Commit and Stack/Heap Reserved values if the Target Platform is 64-bit.

  • The layout of your code is thus entirely different so any memory corruption will influence different things and have different symptoms (or none that may be evident).
  • It will or will not show any pretty dialogs based on configuration options and user settings.
  • For instance, some of the statements after the AV line of code may have already executed, or statements before the AV have not executed. –Aaron Jan 19 '09 at 19:55

Those members are also instanciated using the new operator. weblink A handle covers this condition. If you don't throw from the handler, the handler will just continue and so will the exception. I know best way is not to return this value which seems non-trivial. __try __except

In Visual Studio check Advanced properties of the Linker and your Target Machine needs to be MachineX64 (/MACHINE:X64), that is for a 64-bit Windows platform. but when I change the virtual memory limits, it changes too.

When that memory is no longer valid (it has been deleted or gone out of scope) reset there value back to NULL. Exception Thrown: Read Access Violation. This Was Nullptr. In my program, I'm instanciating classes with the new operator: PLAYER *objPlayer = new PLAYER(0, 0); SHIP *objShip = new SHIP(0, 0); I'm not sure the right way to clean up When the main program is written in C/C++, the C main program needs to call for_rtl_init_ to initialize the Fortran RTL and for_rtl_finish_ at the end of the C main program

Seriously! –Adriano Repetti Jun 12 '15 at 17:26 Guys, I catch this exception so I have chance to log the error, I would still terminate this very process.

Location “0” is in area of memory reserved by our operating system. The correct thing to do is to see why Caller() is returning garbage. It is not possible to catch such "exceptions" in C++. Cannot Use __try In Functions That Require Object Unwinding Thank you, Steve for the note!
