Is that a bad thing? We're only trying to test what the frontend
produces, and if the frontend produces something that the optimisers
realise is a no-op, that's fine.
If any of the ubound()s didn't evaluate to the expected values,
we'd have a call to abort(), and no optimiser has the right to
get rid of that ;)
