Hi Richard,
I think you marked as a duplicate of the wrong bug. It is indeed a duplicate of
82224 - sorry, I didn't realise that there was already a bug filed, also this
test case is "fixed" by version 8.1 and then regresses again in 10.1 (but I
assume that is coincidental rather than the underlying issue was fixed).
