Description (last modified by ryandesign@…) (diff)
As of r92750, the 0.9.9 release of LibVNCServer is being used which includes new IPv6 support.
Now LibVNCServer will attempt to bind both an IPv4 and IPv6 socket for listening. Unfortunately, if one of those fails and the other succeeds for some reason (maybe the IPv6 port is in use, but the IPv4 port is not), the server will segfault as soon as a connection arrives.
This little problem is known to affect the VirtualBox port.
Adding the following to the LibVNCServer Portfile:
# Don't segfault when listenSock/listen6Sock == -1 patchfiles patch-libvncserver-0.9.9-no-segfault.diff
along with the attached files/patch-libvncserver-0.9.9-no-segfault.diff patch file fixes the problem.
The patch has already been submitted upstream (see http://sourceforge.net/tracker/?func=detail&atid=405860&aid=3527807&group_id=32584), but until that appears in a released LibVNCServer version which is then picked up by MacPorts, any ports that use LibVNCServer to create a VNC server are liable to segfault.
