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 https://mariadb.com/kb/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.

It is possible that mysqld could use up to

Hope that's ok; if not, decrease some variables in the equation.

Writing a core file

The server was restarted before the test, so there should be no dependency on previous tests.

The most curious thing about this failure is that it happened before only once, almost 2 years ago, on a different tree (one of 10.0 work trees) and on a different builder, but at the exactly the same place of the test. There is no log anymore, only the failure output:

Retrying test funcs_2.memory_charset, attempt(2/3)...

The test normally lasts only a few seconds, during which it performs the same set of simple actions with dozens of character sets, and greek is somewhere in the middle. I'd say the probability that the failure happened both times on the very same charset by a pure chance is close to zero, there must be something special about greek.
