With `-W -Wall', I get a warning about dividing by zero but I do not think the "Floating point
exception" is a gcc bug because as I said before I did not think this should cause an exception like
the PPC does not.
I found a reference to integer divide in User Guide of IA64 that divide is done in software so this is
really not a bug because gcc does not check for divide by zero which speeds up your program and
there is no way currently to enable this and I think this should not be enabled, you should check
for divide by zero your self.
