Description:
There's a race condition, if a multithreaded up uses the client library.
See bug#13099

As Tim's comment there indicates, the issue needs to be dealt with in individual wrappers/apps.

How to repeat:
See bug#13099

Suggested fix:
From Dean: use pthread_once() or mysql_library_init() in dbdimp.c for threaded environments.
