Description
The attached issue_28287_bad.sql script kills MariaDb 10.2.17. The mysql-error.log contains
2019-08-16 23:14:02 139832664938240 [ERROR] Found wrong key definition in summary_temporary; Please do "ALTER TABLE 'summary_temporary' FORCE " to fix it!

|
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.
|
|
|
Server version: 10.2.17-MariaDB-10.2.17+maria~precise-log
|
key_buffer_size=104857600
|
read_buffer_size=131072
|
max_used_connections=5
|
max_threads=202
|
thread_count=9
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 546245 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went
|
terribly wrong...

Fatal signal 6 while backtracing

The attached issue_28287_ok.sql script is virtually identical but it does not kill MariaDb 10.2.17. Instead the final statement has warnings, the same as in the error log:
MariaDB [test]> show warnings;
