Greetings!  I've checked this out a bit, and it seems as if we may
have run across another SGC garbage collection error, which have
proved exceedingly rare thus far, though I'm not 100% sure.  Just
remove the (si::sgc-on t) command in the save.lisp of the main
nqthm-1992 directory, or alternately fire up the image, do (si::sgc-on
nil), and save to a new version before compiling your pc-nqthm
version.  This works for me for now, but we definitely need to chase
down the apparent freeing of used objects in this example under sgc.

Take care,
