Well, this one isn't terribly short, and it isn't EXACTLY
self-reproducing, but it certainly has that kind of flavor to it.  By
the way, don't even TRY to run this program with a non-infinite stack.
(Hint: try smaller numbers)

@_ = (90470, 482466756, 285076, 95568296); eval ($hack = 's//($_-- >
0) ? ($perl++) && ($hack) : (print "$perl ") && ($perl = "a") && ($_ =
shift @_) && $hack/ee');
