Christopher,
Nice call. Changing the .align let's the exception report
and exit the sim properly ("Terminated by exception.") See below.
Now to figure out how to redirect the exception to a signal handler or
debugger so I can figure out where it came from. Can I hook up
rdimon/FM to gdb w/ semi-hosting? Or perhaps use signal()?
thanks,
Rory

I haven't had a chance to test this out, but I believe the problem may be that
the exception vectors aren't page aligned.
