smbd crash

[Andrej Borsenkow]

30 Nov CVS snapshot (fetched via ftp://cvs.samba.org/pub/unpoacked/samba)

Samba runs with domain security. We have been warned about power supply cut
off and PDC was turned off. SAMBA server runs on UPS and was not touched.
After some time (PDC still being off) I noted nice gdb window :)) Here is
the stack.
