Vladimir,
I just compiled and tested both programs that Paul sent without
problems.
The _BLOCK_TYPE_IS_VALID(pHead->nBlockUse) assertion can get fired
for several reasons. Either memory is getting freed twice, heap/stack
corruption has occured or two(or more) different types of the win32
runtime libraries are been used. In the last case you are not allowed
to free memory in a dll/exe that has been allocated in another dll/
exe if you are not using the DLL versions of the runtime libraries.
Are you linking against the Multithreaded-DLL-Debug version of the
runtime libraries?
regards,
Christopher Raine
