Description
rocksdb.validate_datadic fails on Windows in buildbot:
http://buildbot.askmonty.org/buildbot/builders/winx64-debug/builds/3295/steps/test/logs/stdio
The issue is not easily reproducible.
Based on the above, it fails an assertion here:
mysqld!my_sigabrt_handler [d:\winx64-debug\build\src\mysys\my_thr_init.c @ 488]

This is in mysqld_exit() here:
if (!opt_debugging)
|
{
|
=> DBUG_ASSERT(global_status_var.global_memory_used == 0);
|
}
|
cleanup_tls();
|
DBUG_LEAVE;
|
if (opt_endinfo && global_status_var.global_memory_used)
|
fprintf(stderr, "Warning: Memory not freed: %ld\n",
|
(long) global_status_var.global_memory_used);
|
sd_notify(0, "STATUS=MariaDB server is down");
|
exit(exit_code); /* purecov: inspected */
|
}

An observation by wlad: below, we also see that one other thread is still running, it's here:

this does not look normal. One would expect that at this point the plugin is unloaded and its threads stopped.
- Could it be that that other thread has allocated (and is keeping allocated) something and this is why we see the assert to fire?
