When Community strikes

A few days ago a bug report was filed to the MySQL bugs system. For a few hours it was just one among the many, although it looked hard to reproduce.
Then, suddenly, two experienced contributors, Martin Friebe and Alexander Fomichev, joined the discussion, offering similar cases, explanations, a workaround, and even a patch.

The public intervention took place within 11 hours after the MySQL Engineer asked for clarifications, and within one day the solution was served!

Thanks guys!
We love it when bugs are solved this way.
