[Samba] smbd crashes at startup (3.4.15)

[Holger Trittenbach]

Hi,

I had troubles with samba 3.5.6 so I wanted to test a previous version. I have installed samba 3.4.15 from source but smbd crashes at startup with following output. I faced the same problem with other 3.4. versions.

# smbd -i

smbd version 3.4.15 started.
