Thanks.  That was a VERY fast response!

This solves the problem.  But, I'm mystified, because I could've sworn I =
had
tried exactly that! =20

IAE, I still don't understand why this compiles:

	Tests::TestResultsList* seqResults;
	INTERFACE_TESTS-> Test(seqResults);

and this does not:

	Tests::TestResultsList seqResults;
	INTERFACE_TESTS-> Test(&seqResults);

Clearly, they are very different in terms of execution.  But from the
compilation point of view, in each case the argument is
"Tests::TestResultsList*".  What am I missing?

BTW, I had already realized I needed to allocate the sequence on the heap=
 & I
was going to make the change as soon as I had solved this problem ... too=
 bad I
didn't try fixing that first!
