When my (unsafe) m3 program causes a segmentation fault, I would like
a signal handler to raise a Modula-3 exception.  I've looked at
Usignal.i3, but I've always used signal(3) instead of sigvec(2), so I
don't know how to proceed.  In particular I don't know how to set
sv_mask and sv_flags.  I'm also not sure how to find the bad address
so I can indicate in my exception what address caused the fault.  Any
suggestions would be appreciated.
