[9fans] Irc segmentation fault

[mischief@offblast.org (Nick Owens)]

you probably need to use gcc -O0 -g for that. but it looks like the problem
is in dameonize.c:38. lowering optimization might help since there might be
inlined functions.. haven't really looked at Irc.

If I run Irc in gdb, I get

(gdb) run irc.freenode.org
Starting program: /usr/local/plan9port/bin/Irc irc.freenode.org

which I really don't understand...
How could argc, argv be 'optimized out'?

Thanks for any comments!
