I'm compiling cfengine with uclibc staticaly.
I found that uClibc has a different behaviour compared to standard C lib.
It seems that **h_aliases is NULL under uClibC if there are no aliases for the
host.
Whereas libc initialize an empty array when host don't have aliases.
So this line : for (i=0;hp->h_aliases[i]!=NULL;i++) (nameinfo:417) leads to a
segfault.
The patch bellow correct this behaviour, and avoid segfaults.

Hope that helps
