samba - Mar 2020 - Upgrade 4.9 -> 4.11 oups

Here is some news:

The problem concern this 2 parameters: bind interfaces only = yes + interfaces =
lo eth0 If I comment this 2 lines, smbd is starting (but not listening on
localhost)

We have find our problem source with Denis and figure out that package 4.11.6
from samba.tranquil.it may have been bad compiled (chroot problem ?) No problem
with 4.11.6 from Louis VanBelle ans no problem with package 4.11.4 from
Tranquil.it Denis will work today to check there compilation environment and
publish a new package.

I have also seen this post in febrary " [Samba] smbd fails to start after
upgrade to version 4.11.6" on a rasbian buster. Perhaps also same problem
from bad environment compilation ?
But it's also strange that samba panic.
I will play with gdb today :-) see you later !

There should be more information in the logs than that, can you get some more
context please?  Then set 'panic action = /path/to/gdb_backtrace %d' to
point at this script:
https://git.samba.org/?p=samba.git;a=blob_plain;f=selftest/gdb_backtrace

Install the full debug packages first, so we get a good line number.

Thanks!

Never checked localhost, I will check asap.

I use Louis's packages and get the problem on an rpi4 running 4.11.6, 
but not on a Devuan beowulf (Debian Buster without systemd) running 4.11.6
