Re: Multithread heap assertion failure

HI, all of you,

I have created a Win32 console project with MFC support(shared dll) to
test my multithread programming.
When run, a "Debug assertion failure" occures at the following
expression:
_ASSERTE(_CrtIsValidHeapPointer(pUserData));

I cannot figure out why the exception occurs. Can you shed some light
on me?

Any help appreciated. Thansk in advance.
