This seems like a perfectly reasonable limit, but perhaps the behavior could
be more user-friendly.* Maybe an EXCEPTION_ERR_OVERFLOW should be thrown here
instead?
Using the attached patch to reproduce:
$ perl mktoomanyargs.pl>toomanyargs.pir && ./parrot toomanyargs.pir
Segmentation fault (core dumped)

It certainly shouldn't segfault. But, the question is: why does it
segfault at 206 parameters? Throwing an exception to avoid an error we
don't understand isn't good for the long-term health of the VM.
