[Samba] Samba 3.3.7 -> smbd panic in printing.

[Clément VERET]

Hi everyone,

Recently upgraded to 3.3.7 on a test server (can do everything on it
if you need to test something like patch, configuration options,
etc…), and got big problems with printing very similar to
http://www.mail-archive.com/samba@lists.samba.org/msg97841.html
signaled for version 3.2.6

I'm on CentOS 5.3 recently updated (with sernet packages) and I
checked that I have the correct patch (included in the 3.3.0 release
if I'm right…) with the close_all_print_db(); (in file
source/printing/print_cups.c).

But it still doesn't work. On the official CentOS version 3.0.33, I
installed my printers without any troubles, upgrade to 3.3.7 and then
can't print anymore (losing configurations, etc…). Tried on a fresh
install with 3.3.7 -> same result…

Here is the panic part :

Any ideas on what's wrong ?
