You mean thread_suspendHandler? Perhaps single-stepping through the code 
and having a look where the stack is corrupted would yield some insight? 
Is there possibly some ABI incompatibility caused by callWithStackShell?

sem_post shouldn't cause anything to happen on the calling thread 
itself; and it is explicitly documented to be re-entrant w.r.t. signals.
