[Samba] Memory leak in winbindd

[Ken Cross]

I'm running Samba 2.2.3a on NetBSD.  I've been having an annoying
problem with winbindd dying inexplicably.  I finally found a test that
seems to (eventually) kill it:

  while wbinfo -t > /dev/null; do /usr/bin/true; done

The problem is a memory leak in winbindd.  Actually, wbinfo -t will
still work, but wbinfo -u doesn't (response.extra_data is always null).

Is this a known problem?  Any fixes?
