Ruby overwrites the senderState pointer with another pointer. The pointer is restored only when Ruby gets done with the packet. LSQ makes use of senderState just after sendTiming() returns. But the dynamic_cast returns a NULL pointer since Ruby's senderState pointer is from a different class. Storing the senderState pointer before calling sendTiming() does away with the problem. |
