[debian-mysql] Bug#706072: mysql-server-5.5: Killing a query inside InnoDB causes it to eventually crash with an assertion

Package: mysql-server-5.5
Version: 5.5.30+dfsg-1.1
Severity: normal

Dear Maintainer,

Yesterday I had a bad situation where mysqld crashed and restarted twice
within the span of 20 minutes.  Both times the crash was due to me doing
a ctrl-c to stop a subselect query that was taking too long to run.  I
found what looks like a similar if not exact bug for this on
bugs.mysql.com.  They have it marked as "closed" with no indication as
to if there is a fix etc.

Here is a copy/paste from my daemon.log
