Bug 61534 – BitchX + IPv6 = segfault

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Kingsly John 2004-08-24 10:15:13 UTC]

Bitchx(net-irc/bitchx-1.1-r1) segfaults when I try to  connect to irc.ipv6.eu.freenode.net 

It works fine on ipv4... and my ipv6 connection on the box works with other apps.

Here are the last few lines from the output of strace

socket(PF_INET6, SOCK_DGRAM, IPPROTO_IP) = 6
connect(6, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "2001:1418:13:1::25", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0

I upgraded to 

sys-libs/glibc-2.3.3.20040420-r1

And the problem has disappeared.
