RtlValidateHeap error

Environment: VC++ 4.2b, NT4.0

I recently upgraded to 4.2b and I have one application that is now getting
the following error which I did not get under 4.1:

HEAP (SCMT.exe): Invalid Address specified to RtlValidateHeap (12c0000,6360b8)

The error is occurring in the CWinApp destructor at line 610
   free ((void*))m_pszAppName;

Any ideas on what might cause this or where I should start to look?

Thanks,

Charlie

Did you use m_pszAppName anywhere in your app?
If so, perhaps using strdup() would resolve this error.

This is an easy one.  I'll bet that you are setting the application name =
by setting the value of m_pszAppName.

If this is the case the new CWinApp ctor which now takes a name will =
correct the problem.  Basically the way the strings in CWinApp have =
changed, what you are getting is a failure during the call to free in =
the dtor.  If you are not changing this value then I suspect that you =
are changing one of the strings in CWinAPP.
