Fix 1986/marshall for linux

Choo choo! :-)

There was a problem in linux where it either segfaulted or entered an
infinite loop depending on compiler / flags. This was caused by a for
loop that had an empty condition and the call to _exit().

A game of cat and mouse occurred where fixing it for one compiler caused
the program to segfault with the other compiler. Unfortunately the
formatting did have to change a bit but it still mostly looks like a
train even if not quite as pretty.
