GC-LOSSAGE

[JONL at MIT-MC (Jon L White)]

I'VE FOUND IT!  AND CORRECTED IT!,  Yes, the random
bug in what has turned out to be the bignum division code
was what caused your test program on CF2 to get  a spurious
GC-OVERFLOW interrupt - it seems that indeed in one place
a random register was left pointing to a random cell, which
later got turned into the free-storeage list.  DOes anyone
else think that they may have had a manifestation of this
bug?  By the bye, I ran the test from CF2 for 30 minutes of
CPU time, and there was no GC-OVERFLOW, so I'm sure that's it.
