Re: Debugging with GDB in Linux

[Darren Schreiber]

I sucessfully got past the "not in executable format" error and gdb looked
like it recognized the right file.  But, when I typed run I got "Debugger
segmentation fault."  I logged out and in, tried it from the command line
(instead of within emacs) and got the same thing.

Anyone else having this problem?  (Again I am using Swarm 2.0.1 installed
on LinuxPPC 1999).
