Approved by email with minor comments.

Pushed into 5.0-tree, currently tagged 5.0.18.

[20 Jan 2006 17:20] Alexander Nozdrin

A mistake in the previous post: currently tagged 5.0.19.

[2 Feb 2006 4:59] Mike Hillyer

Has this been merged into 5.1 yet so that a changelog entry can be added for 5.1?

[3 Feb 2006 9:14] Alexander Nozdrin

The patch has been copied into 5.1-release so that it will get into 5.1.6.

The patch is still not merged into the main 5.1 tree. It will get there
after resolving 5.0 -> 5.1 merge logjam.

[6 Feb 2006 13:59] Alexander Nozdrin

Merged into 5.1 tree.

Noted in 5.0.19, 5.1.6 changelogs.

          Improper memory handling for stored routine variables could
          cause memory overruns and binary log corruption. (Bug #15588)
