- Subject: GDB unable to trace xchat on linux
Hello.
I am using GDB 7.5.1 and trying to trace xchat 2.8.8 compiled with
-ggdb and default configure options (see below).
To reproduce:
$ gdb /path/to/xchat
(gdb) r
xchat starts but hangs at "Looking up <insert server used here>".
xchat's faq (http://xchat.org/gdb/) suggests GDB has trouble debugging
when a server hostname is used. As they suggest, I ran a local ircd and
used 127.0.0.1. The problem remains.
Any linux GDB gurus out there that can offer some guidance on what the
problem is?
--mancha
PS. When in this hung state, ^C followed by "thread apply all bt" gives
the following stack. Also after SIGINT and quit from GDB in this state,
xchat's window stays open and the process is unkillable. ps x shows it
in state "t".
