Afaik yes.
But further investigation revealed that only the same ~7 messages stuck
in queue caused these errors.
All affected messages contain some UTF8 chars like (ß, ü, ö) and were
stuck in queue even before the upgrade to 4.95 due to a misconfiguration.
Before the upgrade the segfaults were logged differently and thus I
incorrectly assumed, these were some new errors.
Here's a small output when trying to deliver such a message (recipient:
