I'm sorry for dropping the ball on this, I would like you to open a bug
on this, and send me a gdb backtrace privately.

The Samba sources include a handy gdb_backtrace script, which you can
enable with:

panic action = path_to/gdb_backtrace %d

That will help a lot in understanding what is wrong.

Even as a start, upgrading to samba 4.8.3 will get you a simple
backtrace we can start to at least categorise the error with, but we
will need the full thing from a developer or debug build to really
understand it.

Thanks,

Andrew Bartlett
