core dump when attempting to debug

[jalex]

I recently discovered the following, rather frustrating, behavior
while attempting to debug a swarm app.

The app runs when I invoke it from the command line (or from an
emacs shell), but when I try to inspect it within emacs using gdb, I
get the following:


run gdb (like this): gdb .libs/nash 


Current directory is /home/jalex/prog/swarm/nash/.libs/

(gdb) run
Starting program: /home/jalex/prog/swarm/nash/.libs/nash 

Debugger segmentation fault (core dumped)


Any ideas?  I'd include a backtrace, but I can't:


address@hidden .libs]$ gdb core
