CMSG_DATA returns on my system unsigned char*. Casting unsigned char* to
(ucreds*) and then dereferencing should be a violation of the strict
aliasing rule.

There is an option to turn strict-aliasing completely of using
-fno-strict-aliasing, but it might have speed impact.

I will be back with more...
