How to repeat:
1. Open mysql client
2. Execute, 2-10 times this testcase;
   mysql> source pquery_thread-0.sql_out_out
3. If the issue does not repeat, shutdown and restart server, retry, up to 5 times

See bug #74663

pquery_thread-0.sql_out_out

Attachment: pquery_thread-0.sql_out_out (application/octet-stream, text), 3.36 KiB.

Hello Roel,

Thank you for the report.
Confirmed that only debug builds(5.6.23, 5.7.6) are affected.

Thanks,

Execute this testcase numerous times in the client, quickly after each other. It will crash after 5-30 times paste/paste/paste/...

After the server is restarted, sometimes another crash can be triggered with less statements from the testcase above. It may be that the server is "holding on" to a trx even across mysqld restarts.
