The above sentence is not clear to me; what does the trace below refer
to?  Your original application, or the one that calls ldap_get_option
before spawning threads?  What does ldap_ld_free() have to do with this?
 It never occurs in the trace below.

Doesn't matter.  Global options are global, so multiple threads may find
it uninit'ed, and try to concurrently initialize it.

Please make sure you're calling the desired library objects (libldap &
liblber).  Can you post the result of ldd for your application?
