Hi Guys,

Ok, so this is a simulator bug.
Aldy - these easiest thing for now would be to unilaterally relax the alignment
test in Handle_Store_Double and see if that allows you to get further with your
tests.
(But yes, I agree, a reduced testcase would be a much better help than all this
mucking about in the simulator).
Cheers
