the kernel panic after tcsh here documents is
understood.
Very nice detective work!
The kernel panic is due to a coding error in
mch_fpsim.s. ... After
fixing the "$SIGILL." ... and three similar cases
I'm fairly amazed that apparently nobody has run across one of these 4 before!
(Or, at least, not bothered to report it.)
I wonder how long that bug has been in the code?

New subject: 211bsd: kernel panic after a 'here document' in tcsh
Probably says that that once that most people that ran UNIX purchased the
FP option and did not run the simulated FP and those that did clearly
didn't use tcsh ;-)
Fred Brook's bug's curves really are amazing but are so true. Some really
major bugs just take years to be discovered because no one ever looked and
when you do. It can be like this one -- 'wow!'
