In cases like this, I ask for the minimum program which shows the bad behavior.
In most cases, in triming down the extra code, someone finds the problem 
someplace else.  If it's a 20 line program which shows the bad behavior, it's
very simple and quick for me to diagnose what the problem is and potentially
fix it.  For example, the program may be using a null pointer, which will
work under Windows but page fault under CWSDPMI (this is a program bug that
CWSDPMI catches that you can't under Windows).
