gdb stacktrace causes running queries to abort

Asked by Greg Hazel on 2011-07-03

Simply attaching gdb (then detaching immediately) to a running Percona mysqld instance causes Percona-server to disconnect clients with running queries. Clients get "Lost connection to MySQL server during query" but reconnecting works fine and the server seem to be healthy after that.

Percona-server 5.5.13, CentOS 5.6, gdb 7.0.1

Interestingly, it does not happen with original mysqld (5.5.10).

Has anyone seen this?
