Segfault in 3.0alpha20 [woeltgens@physik.rwth-aachen.de: Bug#171823: Segfault in Samba]

[Steve Langasek]

Hello,

I'm finding that setting a default panic action in smb.conf has been an
effective tool for finding out about segfaults that users wouldn't
report otherwise. ;)  Below, please find the first of several reports of
segfaults in Samba 3.0alpha20.

If anyone recognizes this (or others) as a bug that was fixed in alpha21,
please let me know; otherwise, I'd be obliged if someone was interested
in taking a look at these crashes.

Cheers,
