I should like to see some evidence, then.  Post a complete, compilable
program; the command you use to compile it; and the complete output you
get when you run it.

Sorry for seeming suspicious, but a perfectly reasonable (to me)
explanation has been posted several times, and I haven't seen anything
that refutes it.

Ok, then I think the FDIV bug can be ruled out.  AFAIK it was only in
models up to about 90 MHz.  Did you try the test program?
