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.
