severity 631729 normal
retitle 631729 irssi-plugin-xmpp: segfaults when connecting to local Prosody
tags 631729 + unreproducible
thanks

Hi Adrien,

I'm lowering the severity of this bug, so that it no longer blocks
migration of irssi-plugin-xmpp to testing, because

1) this is no longer the issue that was originally reported (memory
corruption)

2) unlike the original issue, it doesn't occur under all circumstances
and for all xmpp connections

3) I'm unable to reproduce the issue, neither when connecting to a local
Prosody freshly installed, nor with the prosody.im server.

No part of this is irssi-plugin-xmpp itself. lm-socket.c is from
libloudmouth, I believe. Which versions of irssi, prosody, libloudmouth
are you using?

$ dpkg -l '*loudmouth*' irssi irssi-plugin-xmpp prosody
ii  irssi                0.8.15-5    terminal based IRC client
ii  irssi-plugin-xmpp    0.52-1      XMPP plugin for irssi
ii  libloudmouth1-0      1.4.3-8     Lightweight C Jabber library
ii  prosody              0.8.2-2     Lightweight Jabber/XMPP server written in 
Lua

And you're on i386, whereas I'm testing amd64, right?

If I've misunderstood you and you *do* still get "double free or
corruption" (rather than a segfault), please try running irssi under
valgrind as KiBi suggested, but connecting and authenticating to my
local prosody, I don't see any issues...
