I thought you meant change the input to something that would be
stable, ignore me.

I did that, and made no difference. Either because the current order
is just right (and the old wrong, but I can't test it), or because it
was never hit and the stability of the sort wasn't the one to blame,
but the order in the indexed array.

Since those cases were also happening on Intel, I haven't spent that
much time on those and left them for later...

That's ok, I hope the sqlite3 issue can be solved with the round() function.

I'll update you on my progress, so that we don't work on the same
thing at the same time.

PS: the fpcmp bug: http://llvm.org/bugs/show_bug.cgi?id=15620

It's possible that sqlite3 can be fixed *only* by fixing that... I'll wait
