Yes. Thank you(!) I originally found out it crashes before
mainCRTStartup
by running it through gdb after reading the cygwin FAQ. As it runs on
both
Linux and Solaris I assumed it would be a compiler quirk. I'm not
altogether
sure how I debug code that appears before the stuff I've written.
gdb tells me:
Program received signal SIGSEGV, Segmentation fault
0x77f0528c in ?? ()
Any further assistance would be apreciated.

That address denotes a system DLL. When the program is starting in
GDB it prints the load addresses of the DLLs as they are loaded.
This should show you which DLL is having a problem.
Another thing to do is to run 'cygcheck' to see if it reports anything.

Many thanks for your insight. You'll be happy to hear that my program
is
now a happy bunny.

This would be one of the many cases where running the program under gdb
would probably prove useful.
That's how you debug programs on UNIX and it's how you debug programs
under Cygwin, as well.

I am currently trying to convert our companies product from various Unix
systems. I am trying to compile one program (that is archaic) & works
fine
under Linux, Solaris etc, etc. Under Windows it crashes before it gets
to
main(). I think it also crashes before it gets to mainCRTStartup(). If
I set
"STRACE=1", then run the program I get no debug output (it crashes
before even that
kicks in). Does anybody know what might cause this or how to fix it?

That's how you debug programs on UNIX and it's how you debug programs
under Cygwin, as well.
