This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
 
To report this bug, see http://kb.askmonty.org/en/reporting-bugs
 
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.

These are problably not regressions, as at least connect.bin failure is visible in e.g. the 10.0.15 build logs

Is it still happening?

Comment by Otto Kekäläinen [ 2015-09-25 ]

Latest Debian build status is easy to check from https://buildd.debian.org/status/package.php?p=mariadb-10.0 at any time.
