<p>it's just a guess without a backtrace, but it looks similar to an
already known issue of a double mysql_close. The code has not yet
in a release but it's in the master-2.3 branch. If you are
building from source you might be able to patch it yourself while
waiting for the next 2.3.x release.<br>
