#16698 new defect

IRC protocol crashes on suspend

Reported by: ari Owned by: elb
Milestone: Component: IRC
Version: 2.10.11 Keywords:



I use Pidgin's IRC feature. Occasionally when the network disconnects, Pidgin crashes. This bug can be easily reproduced by running Pidgin, signing in an IRC account, and send the computer to sleep. Pidgin is guaranteed to crash upon resuming.

Program received signal SIGSEGV, Segmentation fault.

I'd like to see if this still occurs with no plugins loaded. The crash is on the free of irc->motd, which really should not be problematic.

Looks like the same crash happens with no plugins loaded.
