On (my) Solaris 8 the man page of thr_yield() says that it "... returns nothing
and does not set errno"; in thr_posix.c, however, the code looks like

#elif HAVE_THR_YIELD
        return thr_yield();

I assume

#elif HAVE_THR_YIELD
        thr_yield();
        return 0;

would be more appropriate.  Otherwise, the behavior is unpredictable when
LDAP_THREAD_DEBUG is defined.
