^ Found warnings in /var/lib/buildbot/maria-slave/work-opensuse-amd64/build/mysql-test/var/1/log/mysqld.1.err

It's the only test that currently fails in the valgrind builder on 5.5, so it would be really nice to have it fixed.

Log writes are done using static block sizes, clearly sometimes the end of the block is not initialized. However, this code is not familiar to me and my fix tries did not resolve the issue.

Serg: Any suggestions how to find where exactly the unused bytes from block(s) remain uninitialized ?

I don't know this code either. In cases like that (when there's a lot of unfamiliar code) I'm trying to reduce the amount of code to look at. With git bisect you can find what exactly commit has introduced the bug. Hopefully it'll be small enough to understand what went wrong.
