gdb not recognizing core file format

[Robert Reif <reif@magicnet.net>]

Hi,

I'm trying to use gdb to get a stack trace on a program
that is dumping core without success.  Is this a known
problem or am I doing something wrong?  The program
is compiled with g++ using -g.

Here is the output from file and gdb:

core: ELF 32-bit MSB core file, (signal 11), SPARC, version 1 (SYSV),
from 'test'
