This is what's causing the segfault in libpthread.so
I can only imagine that the same thread is trying to re-lock a single-lock 
mutex. So my code should be something like:
int already_locked_meth = is_already_locked(rand_meth_lock);
int already_locked_engine = is_already_locked(rand_engine_lock);
if (!already_locked_meth)
    	CRYPTO_THREAD_write_lock(rand_meth_lock);    	
if (!already_locked_engine)
    	CRYPTO_THREAD_write_lock(rand_engine_lock);
/* DO STUFF */
if (!already_locked_meth)
    	CRYPTO_THREAD_unlock(rand_meth_lock);    	
if (!already_locked_engine)
    	CRYPTO_THREAD_unlock(rand_engine_lock);
