Please show a backtrace.

This assertion means: pthread__add_specific() is called with a key that
has not been created properly (and this is most likely called from
pthread_setspecific() with the key passed from the caller).

The manual says:

     Undefined behavior may follow if either function is called with a key
     value not obtained from pthread_key_create(3), or if the call is made
     after key has been deleted with pthread_key_delete(3). [..]

Since it only happens when you quit the program, my guess would be some
cleanup calling pthread_key_delete() and later some other code still using
the key.
