Description
Sometimes mysqld crashes leaving a dmp file, which can be used to output stack traces, local variables etc on buildbot
However mtr is not using it . It used to do so in the past, and would cdb debugger (which is installed on the machines) which would produce a lot of helpful for troubleshooting information
Recent example of mysql.dmp found and ignored.
From http://buildbot.askmonty.org/buildbot/builders/win32-debug/builds/2033/steps/test/logs/stdio

The result from queries just before the failure was:

drop table t1;

drop table t1;
