Miguel, have you tried with 5.5.25 official Oracle binaries as I did?
[21 Jun 2012 0:40]
Jervin R
Not sure why this is still marked as can't repeat - have you tested with official Oracle binaries yet?
[20 Jul 2012 3:23]
Jervin R
The problem still exists on 5.5.25a, not sure why this is still can't repeat?

This is a know bug that is fixed in current code:
macbook-pro:5.5 openxs$ bin/mysql -uroot test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

So, please, wait for the official release of 5.5.27 with the fix.

Valeriy, Thanks - looks like Miguel tested with 5.5.26 - is this coming to .26 or .27 as you mentioned?

Ahh, nvm, found my answer :) http://dev.mysql.com/doc/refman/5.5/en/news-5-5-26.html
Description: When SELECTing from a timestamp based range partition where the table has no partition to handle values less than MAXVALUE and the SELECT condition reads from the last partition or greater, mysqld gets a signal 8.
