Hi All, This is just a heads-up that we've run into quite a horrible crash + data corruption issue with MariaDB when running sysbench with a large number of threads on a couple of AArch64 platforms.

I believe the problem can be attributed to the code used to release the custom mutexes used by the storage engine.

I have logged a ticket (and attached an emergency fix) here: https://mariadb.atlassian.net/browse/MDEV-6615

Sorry for replying to an old message, but I noticed this was recently reintroduced in MariaDB: https://mariadb.atlassian.net/browse/MDEV-7658

And also is unfixed in MySQL upstream (we've pinged Oracle about that): http://bugs.mysql.com/bug.php?id=76135

Not very encouraging to see "fixes" being introduced with

#ifdef __powerpc__ ... #else /* On x86, we don't need that... */ #endif

Do we have anyone on the list even peripherally involved with MariaDB/MySQL development who could help with reeducation?
