ok, thanks for pointing out the setup to test. Indeed there seems to be
a problem with the interpretation of matrices.
Please, open a problem report in the Bugzilla system, so we can further
investigate and track it.

Can you please provide the use-case you refer to for reproducing the
problem, indicating how you associate the auxiliary information in your
code ?  I'd suggest you specify all this directly in the problem report
in Bugzilla. Thanks.
