Some of you may be aware that MySQL is increasingly using an Oracle-internal bug tracker. You can see these large bug numbers mentioned alongside smaller public bug numbers in recent MySQL release notes. If you’re particularly unlucky, you just get a big Oracle-internal bug number. For a recently fixed bug, I dug further, posted up on the Percona blog: http://www.mysqlperformanceblog.com/2011/11/20/bug12704861/
Possibly interesting reading for those of you who interested in InnoDB, MySQL, BLOBs and crash recovery.
