Eric,

I'm not sure I can explain all the whys of this, but it appears that other senders of #doPrimitive:withArguments: were from methods where the arguments were already on the stack (your error hapens trying to copy from this stack into the interpreter proxy).

I converted your snippet to a class method:

=================================================================
'From Squeak3.5 of ''11 April 2003'' [latest update: #5180] on 2 September 2003 at 6:01:53 pm'!

!MyPlugin class methodsFor: 'as yet unclassified' stamp: 'raa 9/2/2003 18:00'!
TESTinnerLoopX: a y: b limit: c

	^MyPlugin doPrimitive: 'innerLoopX:y:limit:' withArguments: {a. b. c}! !

=================================================================

and, now,

	MyPlugin TESTinnerLoopX: 1 y: 1 limit: 1

will run.

Cheers,
Bob
