Bug #65663 Signal 8 When Selecting with Range Greater than Last Partition

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.

Repeatable with 5.5.23, 5.5.24 and 5.5.25, NOT with 5.5.20, 5.5.21, 5.5.22

How to repeat:
[revin@forge msb_5_5_24]$ ./use test

You can turn off this feature to get a quicker startup with -A

Suggested fix:
NA, but a workaround is to add a partition to handle values less than MAXVALUE.

Thank you for the bug report. Indeed repeatable with 5.5.24 but not anymore with current source:

Miguel, have you tried with 5.5.25 official Oracle binaries as I did?

Not sure why this is still marked as can't repeat - have you tested with official Oracle binaries yet?

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:

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
