Fatal numbers bug


Current CVS versions of guile have a major bug in numbers.c: scm_flo0
is not protected from gc! (I spent an hour or two trying to find out
why the changes from ice-9 to guile were causing disgusting things to
happen with guile-gtk). This fix is against the current cvs tree, the
version of numbers.c in the boot-9.r4.tar.gz package can be fixed in
the same way. If you've been noticing wrong-type-arg errors with
#<freed cell foo; GC missed a reference>, this could very well be
what's causing the fuss.
