Irssi segfaults upon /part or, sometimes, a server timeout #885

Open irssibot opened 11 years ago

irssibot commented 11 years ago

Hello all,

The segfault corresponding to the attached backtrace happens when I type /part in a channel. I also, sometimes, get a segfault when the connection to a server times out. I couldn't get a backtrace of such a timeout yet, so I can't tell whether they are related.

Operating System: Slackware 13.1 64-bit Irssi version: 0.8.15

The build scripts that are used by Slackware can be found here: http://mirrors.slackware.com/slackware/slackware-13.1/source/n/irssi/

Be aware that this applies two patches, although I think it's unlikely that they cause the segfault... especially the man page patch :-)

bitlbee_rename.pl (with a small modification) bitlbee_typing_notice.pl booleansoup.pl (custom) dinnertime.pl (custom) heart.pl (custom) hilightwin.pl lastfm.pl nickcolor.pl screen_away.pl trackbar.pl zosma.pl (see https://github.com/DeltaLeonis/botsma/blob/master/zosma.pl)

I'm hesitant to add the contants of the custom scripts and the irssi config file, as they might contain sensitive data. Providing the full backtrace is already a little revealing.

The offending script turns out to be the attached one.
