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

Still having the issue of FM/semi-hosting not catching seg-faults using 2013.06. With "aem-ve.specs", a fault seems to call main() repeatedly. With "dimon.specs", FM hangs. Any ideas how to properly compile/deal with faults in semi-hosting mode?
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.
