Hello,
Thanks for the report. I recommend that you submit it as a bug report to
avoid all chances of it getting lost.
The acl code was totally rewritten for this release, and and in looking
at the code, I see that there is no implementation at all for OpenBSD,
not even an empty implementation, which leads to the seg fault.
I will contact the author to see if he has a solution. In the mean
time, I suggest that you comment out all
calls to jcr->xacl-> ...
Best regards,
Kern
