Re: [gambit-list] Fix garbage collector bug on 64 bit systems

Marc:

In lib/mem.c you changed

@@ -345,7 +345,7 @@ ___HIDDEN long words_prev_msections;

/* words usable in msections */ #define WORDS_MOVABLE_USABLE \ -(2*the_msections->nb_sections*((___MSECTION_SIZE>>1)-___MSECTION_FUDGE+1)) +(2*the_msections->nb_sections*(long)((___MSECTION_SIZE>>1)-___MSECTION_FUDGE+1))

Perhaps your intention was to ensure that some part of the computation will be done in 64-bit arithmetic, but on 64-bit Windows I believe (but am not sure) that (long) is 32-bits, and that you need (long long) to get 64-bits.

One should probably use a 64-bit type defined in gambit.h.
