In the CVS Guile, I notice that scm_cells_allocated is now signed.
When I run Snd over its test suite, more than 2^31 cells are
allocated, I guess, because gc-stats now reports cells-allocated
as -312113.

no, there I think there is a bug in the stats routines. (I've been
mucking with it.) 2^31 cells is really a lot of memory, I doubt that
you would have that in a test suite.

Yes, that's another Brown-Paper-Bag-Bug that I introduced (which I
fixed in CVS). I should pay more attention when working on such
fundamental things like GC.

I fixed the unsigned part; can you check whether this gives meaningful
results for you? (I find it hard to believe that you allocate 2^31
cells -- but it might be possible.)
