_CrtIsValidHeapPointer error

[chikach]

hai This started happening when I added a malloc and free. I checked in Debug it is while freeing the memory. I tried the runtime lib settings.It was initally /MDd that time this error _CrtIsValidHeapPointer was coming.Then I tried to changed to /MTd then it in call stack shm_test.exe1_unlock_fhandle( ) was there. chikach

I m getting CrtIsValidHeapPointer debug assertion

There is a discussion of this assert here[^], but it basically means that somewhere in your code between malloc() and free() your memory pointer has been corrupted. Try stepping through your code with the debugger to see if you can spot where this is happening.

It's time for a new signature.
