Hi,
I've been using gdb on UnixWare 1 and 2 for a while, but
when I began using it on UnixWare 7, bad things started
happening. I configured it using "./configure", and I did
configure/re-compile it on UnixWare 7 just to make sure
there weren't any incorrect dependencies on UnixWare 1 or
2... Basically it doesn't like the format of the core
file. I've attached a shell script, as well as the output,
which reproduces the problem in a simple way. Any help you
can give me would be greatly appreciated. Thanks.
-Russ
P.S. I can send the executable file and core file if that
would help.
