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: Script started on Sat Jun 28 18:38:10 2003 [101] galen@andromeda:~> gdb GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.

(gdb) apropos REGEXP string is empty (gdb) apropos foo Segmentation fault (core dumped) [102] galen@andromeda:~> exit exit Script done on Sat Jun 28 18:38:23 2003 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 __________________________________ Do you Yahoo!? SBC Yahoo!
