.... and that's what happened. Before applying your
fix,

osize was 32 (which presumably is actual size +
sizeof(gc_unit))

size was 20; sizeof(gc_unit) is 16 (2pointers) and
16 > (32 - 20) was true.

After applying your fix, make check runs fine;
ofcourse it fails on 19 tests. But, *this* I believe
is the right fix :-) (as opposed to my previous "fix")

Thanks for your help.
