I am developing an application that sends and receives messages

sending and receiving to be able to debug my code. TOSSIM simulates
the sending operation correctly but it can't simulate the receiving
operation. Here is my code for the receiving:
event TOS_MsgPtr ReceiveCtrlMsg.receive(TOS_MsgPtr m)
{
CtrlMsg *ctrlMessage = (CtrlMsg *)m->data;
struct CtrlMsg *msg;
This is a bug. You have allocated a CtrlMsg*, not a CtrlMsg. Since
the pointer is on the stack and you have not initialized it, who
knows what it points to.... This is a basic C bug and has nothing to
do with nesC/TOSSIM.
