Package: irssi-plugin-otr Version: 0.3-2 Severity: important This plugin periodically segfaults my entire irssi session, which is very unfortunate.
I recompiled with debugging symbols and ran it in gdb until I received a segfault, which I am including below. it looks like maybe the issue is an int overflow: len=-1212702368 as can be seen in this line: #2 0x080d8e77 in linebuf_append (rec=0xb7b7a160, data=0x2bc <Address 0x2bc out of bounds>, len=-1212702368) at line-split.c:49 This line seems odd as well: #11 0x080ac2ff in irc_parse_incoming (server=0x8220d30) at irc.c:378 str = 0x8213988 ":[email protected] PRIVMSG micah :RypQu8Crqcecm+LLvZsE9c0Y0Wc3jizK7zgc7qA2BiU14LFCOc+t2qPzPLU5Q7Q3DlIBiYctp0O3pdUcFyoj6gJaT8fTFggOo2qQXaNnqb36hM2W22JZvn3F+CNht3EZPndNV4e9voCrUqlyjj0LdvssPBTgrzIutTvr"... count = 10 ret = 1 count=10 is strange... in any case it seems like irssi_io_invoke seems to screw things up and irc_parse_incoming might have some issues as well. if any of this is right, then misc.c line 54 and potentially irc.c line 378 are probably good places to start, but I'm not sure if my analysis is even correct. Anyways, here is the gdb backtrace (with names/messages changed to protect the innocent): Program received signal SIGSEGV, Segmentation fault.
