If your program runs in a Windows DOS-Box, but causes a page fault in DOS or DOSEMU, then there's a good chance that it erroneously uses a NULL pointer for memory access. This is a pretty common error, and AFAIR there is a switch for cwsdpmi to disable the "page 0 protection". You can also test with HDPMI's -m switch: C:\>HDPMI -r -m C:\>your_program.exe If your program runs in this configuration without page fault, there is a "forbidden" NULL pointer usage inside your program. ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
