Re: [squid-users] Massive crashes with 3.2.6 "assert "false" at line 689 Ip::Address invalid? with IsIPv4()=F, IsIPv6()=T"

Hi ralf, i also have this problem under OpenBSD 5.2.
Here is my fix, you have the same problem as me. Amos please use my
patch !! (now i get more than 1 day uptime, instead of 5min uptime...)

http://bugs.squid-cache.org/show_bug.cgi?id=3732

This remove the assert and manage the getaddrinfo result on this
function :)
