Always at the same code:

I have almost no information about why/what happened. But I control all the clients that can legitimately connect to this server, and none were running at that time. So it must have been caused by random attacks from the internet.
More may have occured earlier, but that syslog is gone. Some crashes came in packs of 1 to 4 during less than a minute, no noticeble pattern in rythm.

I find it worrying, that apparently random connections from the internet cause segfaults, hence this report.
