A little under one hour after upgrading from 4.94.2 to 4.95 on FreeBSD
12.2 I see this happening on a virtual machine (no jail) of mine.

I briefly checked the dev archives (not subscribed) and bugzilla, but
found nothing more on this topic.

Before I go crazy with all the debug-options, were you (or anyone else
in this thread) ever able to determine the cause of these SIGSEGVs?
