mathlink program hanging in MLAnswer

I have a mathlink program that hangs in MLAnswer. The program gets
through all of my code and then hangs in MLAnswer within the mprep
generated tm.c file on the line

while( !MLDone && !MLError(mlp)
	&& (pkt = MLNextPacket(mlp), pkt) && pkt == CALLPKT){

on the second pass through this loop.

Stepping through the code, I find that it hangs on the second "Step
Into" on this line, perhaps this suggests the MLNextPacket(mlp) call.

The program enters an infinite loop within MLMAP32 bouncing between
lines
01193D88   mov         eax,dword ptr [esp+10h] .
