I agree that it appears that the Mozilla code had a serious bug/flaw,
and that having the FP traps enabled caused that fact to become
apparent.

But the issue for me is still one of standards conformance.  Regardless of
how helpful enabled FP traps may be, on occasion, for certain programs
and/or certain programmers, the IEEE 754 standard is pretty darn clear
and unambiguous regarding what the default setting should be, i.e. all
traps disabled.
