Was having a crash with 2.13/CVS ld; this change has fixed it

<       bytes = (size / file_align + 1) * sizeof (boolean);

   The realloc a few lines below was crashing. Perhaps the memory block
was trashed past the end? Since the ptr is stored as ptr-1, perhaps the
extra +1 is needed to make up for it (the other +1 is because if you
want to index data at 7, you need 8 bytes...)
