[Samba] nmbd crash on z/800 64 bit RHEL v 3.0

[Eric Wilson]

Hi All;

I'm currently trying to expand my Samba env by including my IBM z/800
mainframe running 64 bit RHEL v3.0, CUPS printing environment into Samba.

When I start Samba, the nmbd dies almost immediately.  Any insight would
be greatly appreciated.
