:-) Lemme give a little more background.
I'm working on patches to glibc so powerpc can be configured entirely
with soft-float (exceptions and everything simulated). They use the
glibc/soft-float/* functionality, plus some glue code I've written.
So... The SIGFPE is definitely being caused by my hacks, not by the
kernel or the hardware :).
I just want to track down where exactly it got generated.
