That's right.  Excellent.  Then I think we understand exactly why
these failed.

Yes.  We're working with the HDF5 guys to come up with better versions
of these tests.  Thanks much for the report!

These are new tests with 1.6.6, and I think we know why these fail.

I think these tests used to pass in 1.6.5.  I'll double check them.

Thanks again!
