>Description:
mDNSResponder will crash occasionally when used on a network with IPV6-capable Mac OS X hosts:
Assertion failed: (0), function recvfrom_flags, file mDNSUNP.c, line 665.
This seems to be caused by a wrong/stale set of #defines in mDNSUNP.h
>How-To-Repeat:
Run 'mDNSResponderPosix -v 2'
>Fix:
