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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information

Hello Mr. kevin,

Thank you for your bug report.

However, you have provided us with sufficient info, nor are you running current 5.7 release. Hence, first of all, try running 5.7.28, because we do not want to chase some bugs that are fixed long time ago.

Next, if you manage to reproduce this, we need a fully repeatable test case, so that we can run it and find the cause of the bug.
