Who did you send the message to? I ported WinAllegro to
RSXNTDJ, but Stefan Schimanski is the one who ported Allegro to
make WinAllegro. If you sent the message to me then I'm sorry,
I can't find it so I must have not received it. If you sent the
message to Stefan, note that he only has internet access at
weekends so can't respond quickly.

What bitmap are you drawing to? If it's the screen, did you
acquire it first? If you don't know what I'm talking about,
read the WinAllegro documentation and my tutorial:
http://www.canvaslink.com/gfoot/winallegro/winaltut.zip
There are some extra things you need to do in WinAllegro.

Don't post the EXE, but do post the code if the problem isn't
solved by reading the documentation. You could also post the
`allegro.log' file, but I have no idea what it means really.

Good, the only way bugs can be found is if people try using it.

I might suspect that there could be a problem with the import
library, but then I'd expect it to be completely wrong, rather
than just wrong in places. However, I have noticed strange
things about this in the past, when making the port; RSXNTDJ's
import library generator was slightly wrong, in a way that
should have made the whole library wrong, but in fact some
things worked fine while others crashed the program. Very
confusing to debug.

Try using the unmodified ld.exe -- in this case it should work
fine. It will pick up undefined references, which could be your
problem (they generate SIGSEGV at runtime).
