Samba dump (useless) core

[Andrea Venturoli]

Hello.

I've got a few servers where I run Samba 4.8 in a jail as an AD DC.

Lately, on a couple of them, it started dumping core: on one server, 
apparently everything works fine after that; on another one I have 
intermittent DNS issues, but I'm not sure they are related to this core.

I tried examining the core, but this is what I get:

The only relevant line, unfortunately is "Core was generated by...", but 
it doesn't help much.

Samba is compiled (via Pudriere) with DEBUG, so I thought the above 
would be more useful.

Any hint?
