Hello all,

I was recently playing around with gdb. I do not use it much but I found that
it had an apropos command. I hoped that apropos would make it quicker for me
to find information about gdb's commands so I wouldn't have to go hunting in
info. Turns out there is a bug in gdb on current where apropos causes gdb to
dump core. I did not build my gdb with debugging symbols but the problem can
be reproduced easily:

(gdb) apropos foo
Segmentation fault (core dumped)

As you can see from the output the core dump only happens when a string is
entered. This is from a world build from sources dated 6/28/03, but I also
noticed it on a world from a week ago.

regards,
Galen Sampson
