You might have to keep trying - or convince your compiler not to do 
tail-recursion elimination.  (I'm a bit surprised, as I've seen the OS X 
gcc do tail-recursion elimination, but perhaps it had a higher 
optimization level when it'd done that.)

That'd be useful - but just iterating a randpkt/tethereal pair found at 
least one problem, namely that, as it's dissecting some SEQUENCE and 
SEQUENCE OF items by recursion, it depends on the compiler doing 
tail-recursion elimination; otherwise, you run the risk of running out 
of stack space.

That might be the problem.  I'll look at getting rid of the recursion.
