Have you tried running it in a single-processor environment (no -mp)?

Yes, gvd works, but it's not a debugger - only a front-end.

Perhaps you use g77? Or a different combination of compiler, debugger 
and compiler options?

That would be very much a problem if gdb does not support the 
environment you run in. Is it an older version of gdb (current is 5.x)? 
Is it 64bit compatible (I guess your software is compilled for 64 bit)? 
etc.
