Comment(by jason):
Ethan,
I've split the issue into two problems: the ComplexWarnings problem that I
hopefully fixed with the patch on this ticket and the invalid division
warning, which I've made #10821. Can you check this code and the
numerical differences in output? I now get these failures:
{{{

It looks like the errors are all slight numerical errors. Can someone
confirm that?
