It's segfaulting in exp, which is not surprising -- I haven't made a
64 asm version of exp.
Disabling all of the tests which use exp(), which includes sinh(),
cosh(), and complex sin and cos,
it fails a couple of other tests:  sqrt(2) for ubyte, and
nextUp(double.min_normal) fails.

I think there might be a compiler bug with the floating point equality
involving implicit casts -- not sure.
But almost all of the tests are passing. Obviously we're very close.
