Description
I'm getting a server crash when I issue a very simple DELETE statement "DELETE FROM companies WHERE CompanyID=749".
I believe it might have something to do with an "ON DELETE SET NULL" foreign key relationship and some indexes of virtual columns in the child table... but unfortunately I was unable to reproduce the problem as a simple testcase; it seems to depend somehow on the data in my existing DB.
I can however reliably repeat the crash if I issue the exact same DELETE statement.
Since I was unable to determine the specific cause, I can't tell if this is related to an already-reported bug or not.
The tables are all InnoDB, and running mysql_upgrade did not affect the issue.
The log contained the following:
190821 4:08:56 [ERROR] mysqld got signal 11 ;
|
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.
