Bug Description

Copy of https://bugs.mysql.com/bug.php?id=86016:

[20 Apr 9:12] Laurynas Biveinis
Description:
MySQL test framework has this very convenient feature of using the debugger to dump any core dump stacktraces. It would be useful to extend this feature to unit test crashes too, as it would help with intermittent crashes there and the like.

How to repeat:
See above

Need to do this on 5.5 as well due to a 5.5 failure on https://bugs.launchpad.net/percona-server/+bug/1684775

The above commits have caused https://jira.percona.com/browse/PS-257

Percona now uses JIRA for bug reports so this bug report is migrated to: https://jira.percona.com/browse/PS-2499
