point: work around GCC ICE in test case
point: work around GCC ICE in test case

GCC experiences an ICE when comparing the components of a redim'd to
lower dimension point. The test case is too complex to reasonably reduce
and submit for fixing/workaround so we add a bit more explicit work here
for this test case only.
