Unhandled Exceptions?

Hi!

I'm trying to understand the mechanisms of interrupt handling in
Pistachio 0.4 on IA32. Now it seems to me that some exceptions aren't
really handled. This includes exceptions like Divide Error and Overflow.
Although interrupt gates for these exceptions are set up (according to
idt_t::idt_t()), the handler basicly constitutes an infinite loop
(exc_catch, src/glue/v4-ia32/exception.cc).

Did I get this right or are these exceptions handled?
If they are, I'd really appreciate a small hint where this is done in
the source code.

Thanks in advance!
