I noticed this problem first time around 19. February with sid. Irssi's
regexp ignores/hilights crashes sometimes - not always and not reproducable,
sometimes it crashes every time doing regexp match and sometimes it can go
long time before crashing. I assume this is glibc bug because I've seen this
same backtrace many times now, and it has always been from Debian users.
Here's an example with ignoring "(away|gone|busy|back|return)"
#0 0x401c39f1 in kill () from /lib/libc.so.6
(gdb) bt
#0 0x401c39f1 in kill () from /lib/libc.so.6

..
The regexp code is:
regcomp(&rec->preg, rec->pattern, REG_EXTENDED|REG_ICASE|REG_NOSUB);
..
regexec(&rec->preg, text, 0, NULL, 0);

Couldn't reproduce it with a bit of testing, hopefully fixed :)
