Yup, and I sent the fix to Brian again today (just for good measure :-). 
If anyone's interested, it has to do with using a single global jump_buf to
implement `return' with longjmp.  This obviously screws recursive functions
or functions that call other functions; the first function to call `return'
gets the right jump_buf and leaves all the others in the twilight zone (I've
seen `main' get re-executed on my IBM RT running 4.3 for a really 
pathological case).
