Running samba-tool domain functionalprep on a running AD DC 4.9.3 leads to INTERNAL ERROR: Signal 11.
Backtrace is attached
Steps to reproduce:
# samba-tool domain provision
# samba-tool domain schemaupgrade
# samba-tool domain functionalprep --function-level=2012_R2
The functional prep command actually succeeds in this case, but for some reason it's crashing in the messaging code with a live server. I think this is a general issue, rather than one specific to the functional prep code.
This issue still exists in current Samba 4.14.5.
I was wondering why this is not fetched by the autobuild (selftest). The reason is, that the command does not fail if samba is not running. That is what the autobuild does.
