    program runs in debug, not in release

    My program runs fine in debug mode. When running a release build, I get following message:

    Unhandled exception in prog.exe (MFC42.DLL):
    0xC0000005: Access violation

    Can someone tell me what might cause this behavior? I am using VC++ 5.0 Pro w SP3

    are ALL your message handlers declared with
    WPARAM and LPARAM
    even if you do not use them they have to be there....

    Re: program runs in debug, not in release

    With me (almost always), I find I have assigned a value within an ASSERT() macro.
    This works under debug but under release the code is not compiled and then I am using an invalid pointer.

    Only the great god ISO knows what happens then. ;-)
