Problem converting application from VS2003 to VS2005

[kphip123]

Hi!

I recently converted an application from VS2003 to VS2005.
The application consists of a main 'unmanaged C++ executable' which
calls
a managed C++ .dll. The .dll basically launches a separate form.

The application use to work fine in VS2003. Now that I have converted
to VS2005 the main executable is working but an exception gets
thrown when it trys to call the .dll (basically the new separate form
never launches). The .dll was compiled with (/clr:oldSyntax).

This is the exception that gets thrown:

File: dbgheap.c
Line: 1414

Expression: _CrtIsValidHeap Pointer(pUserDa ta)

I click on Retry and it triggers a breakpoint at

if ( (oldsize = _msize_crt(*pbe gin)) <= (size_t)((char *)(*pend) -
(char *)(*pbegin)) )
This is the call stack:
msvcr80d.dll!_m size_dbg(void * pUserData=0x1ba 3922e, int nBlockUse=2)

I already checked and made sure that both the .exe and the .dll we
compiled with /MDd.
any help would be much appreciated!!!
thanks

You'll want to ask on a MS forum. This one is for C++ language proper.
