I have isolated a problem with my machine that I would appreciate
some thoughts on fixing. I have a simple program that should get
a segmentation fault when it accesses reserved memory. However,
instead of performing the error detection and handling, the machine
just crashes. I would appreciate some advice about how to isolate
the real culprit. This same program works fine (segmentation faults)
on the tahoe at albany so I think it is a local problem. 

I compiled the program on the albany machine and brought the binary
back and that still crashed my machine so it seems to be in the
error handling.

I am including the program here but am omitting the reserved address
for security reasons. If you want an address to put in there that
crashes my machine you can contact me directly.

	main ()
	{
	asm ("movl  $0x????????,r0");
	asm ("cvtbl 4(r0),r0");
	}

Thanks in advance,
	Gretchen
