At first (very quick) glance, I can't help thinking that this last line
ought to be
	qTable _ self fetchArray: 4 ofObject: rcvrOop
since you've just carefully made 'rcvr' be the int* to the first
indexable field. Since rvcr isn't actaully an oop, the
fetchArray:ofObject: is quite likely to have some trouble.

I would recommend you consider a minor rewrite to make your plugin a
subclass of TestInterpreterPlugin and then you can use a slightly
'cleaner' style to get your arguments sorted out that would probably
help a little. Look at the subclasses of TestInterpreterPlugin for
examples.
