Storing cooked crabs outside overnight

We didn't have enough room in the refrigerator to store our cooked dungeness crabs so we stored in on the balcony. It's cold here, I'd say about 49 degrees last night. Would you say its safe to eat them?

Normally a safely cold refrigerator is set at just above freezing temp. Our's is at 36 degrees F. 49 just doesn't seem like a safe temp. Were they fresh or frozen solid when you put them outside? If frozen (ice-frozen) and still frozen in morning, I would say go ahead. However, if they were not in a frozen state and closer to fresh, I wouldn't take any chances at only 49 degrees.
