And now we have a delicate but deterministic crash building STABLE on
the Alpha (see yesterday's nightly build message). Hrm. (It's
delicate in that if you run the compiler slightly differently -- with
command-line arguments ordered differently or with .hi present, etc.
-- the crash moves or goes away.)
I would be very happy if either (preferably both) of these bugs are
due to using data from below the C stack pointer at some stage. But!
I don't see where the C stack pointer is touched other than in
(off to turn off the virtual timer in the HEAD build to see)
