Well, partly. I found out that it works if I start it in wine "wine app.exe".
But if I start it with "winedbg app.exe" I still get this exception. So after
all it's maybe not an msvcrt fault but a winedbg one. Maybe because
it's catching every exception immediately even if it would be handled later
by the program.

To find out what's going on inside the MFC I added all MFC-sources to my
prg. Here's the new bt with MFC-files (original file names from MSVC6).
The original MFC42.dll is loaded because of the ocx.

What is this error that is showing up while loading the files?

Error: Copyfield list mismatch (4<>3): enum CTestocxCtrl::__unnamed struct none

Maybe this has something to do with it. Using wine from cvs 2002-10-11 with 
all builtin.
