The implementation you're using (gssglue) is part of the Linux NFS
project, so you might try their lists; see

The segfault sounds like a bug in gssglue or an indirect result of a
memory corruption bug in your code. There's no reason you wouldn't want
to release the name after a failure from gss_acquire_cred. I looked at
the gssglue sources but didn't see anything obvious.
(Is "gas_" just a typo for "gss_" everywhere you used it, or is there
some meaning to it?)
