A cheap tactic.

If I cannot produce a satisfactory counter-example then that somehow
will discredit all that I have said.

Well, I am not going to provide a SPECIFIC counter-example.  It may
take a while for me to procure one, and I have other fish to fry as
well.

But here is an excerpt from the Intel ICC manual:

"Using the default option keyword -fp-model fast or /fp:fast,
you may get significant differences in your result depending
on whether the compiler uses x87 or SSE2 instructions to implement
floating-point operations. Results are more consistent when the
other option keywords are used."

Who am I going to believe?

Hint: It's not you.
