A patch for this bug has been committed. After review, it may be pushed to the relevant source trees for release in the next version. You can access the patch from: http://lists.mysql.com/commits/62681 2729 Davi Arnaut 2009-01-08 Bug#41889: Test main.innodb_bug38231 is failing w/embedded server (server crash) The problem is that a mysql connection instance is not thread-safe and reentrant, meaning that it can't be used concurrently and can't be re-entered while it's already running. This applies for any form of the server (embedded or not), but this rule can be violated in a test case if the test sends a new command without waiting for the result of previous command that was sent asynchronously and this can lead to hangs when over a network or to crashes under embedded server as the server query execution path will be re-entered concurrently with the same connection structure. The solution is to rework the test case so that the aforementioned rule is obeyed.

Patch looks fine. It would be nice to have this checked in mysqltest.c (die with an error if --send is active and another query is attempted).
