Subject: repeatable ircu crash

Hi there,..

I just found a repeatable way to crash ircu.

on phoenix.az.*, running
u2.10.04.resolv9.nmt.egcs4.tok.pten.tlim4.admin.upper4.whisper3.gipl.modeless7.
phoenix.az.us.undernet.org :M07B7eEIKMpRSt

I did the following:

/topic #macintosh,#mac ShadowIRC 1.0.1 released: <http://www.shadowirc.com/>

I was on both channels, and a third, #macdev.

phoenix core dumped. When it came back up, I did it again to confirm, and
it cored again.
