Yes.  It will occur whenever a subroutine call requires too many
registers to hold all the intermediate results before putting them
on the stack.  Someone's register reclemation algorithm could
use a little fine tuning.  In particular, constructs like

	a = foo(bar[i].left, bar[i].right, ... );

will get the error.  However, it can be recoded as

	t1 = bar[i].left;
	t2 = bar[i].right;
	...
	a = foo(t1, t2, ... );

What a hack eh?

Oh yes.. There is documentation on how to do this supplied with the
compiler, but..

	(a) initialize a new disk
	(b) copy everything but hos.tos to this new disk. DO NOT
	    USE A SECTOR COPY.
	(c) To run, boot on HOS.TOS on the supplied disk, eject it
	    and insert your copy.  You should do a 'ls' to get the
	    new disk directory information set up properly.

NOTE: If you have a one drive system, go an borrow a 2 drive one for
step (b).  There are 40 or so files that have to be copied, 3 disk
swaps per file = 120 disk swaps.

They suggest that you do not use a sector copy.  I would assume that
their protection mechanism either (i) will cause the sector copy to
abort, or (ii) foul up the protection on their disk.
