A "side-effect" of Tobias Burnus' fix for PR92996, which addressed simplification
of some array-valued constant expression, is that it fixes the ICE in the subject.

To make sure that we do not regress I committed the testcase below as rev.279699.
This was OKed in the PR by Thomas König.

Thanks,
Harald
