Yes, the problem now stems from floating-point comparisons not
working, which causes the Hashtable constructor to reject the
loadFactor argument.

I *think* this stems from renumbering the registers, which is looking
to be more and more bogus. So fixing the register allocation is the
thing to do, not kludging around it.

But that's for next week.

You've been more than helpful already; thanks.
