socat crashes on OBS build host when trying to listen or writing UNIX domain
sockets. It happens mostly on ppc or armv7l only. socat from openSUSE 13.2
works. Seems the bug is fixed in 1.7.2.4

I'd like to prepare a maintenance update from socat 1.7.2.2 to 1.7.2.4 if that
would be ok.

Reproducible for example like this:

$ socat -u UNIX-LISTEN:socket,fork,max-children=1,backlog=128 STDOUT > outfile
$ socat -u /dev/null UNIX-CONNECT:socket

...*** stack smashing detected ***: socat terminated
