This is the application from bug #15824. I found a standalone installer which
doesn't have bug #34982.

Installation and launching the application goes without problems, I can connect
to a server (irc.freenode.net), MOTD is shown, but the chat client crashes when
I try to join a room (e.g. #winehq). 
I entered the same room using Pidgin on Linux and noticed that the user I
created in CChat entered the room but immediately left (because the client in
Wine crashed).

The same problem with Wine 1.2/1.4/1.6.
Tried with native riched20, but it didn't help.
