Passing this flag fixes the issue, so I'm going to do that (are there any downsides?) It seems like a non-64-bit-compatible bitmap was being created, and that doesn't have the bitmap->bitmap_ops field initialized because gen_bitmap.c doesn't use this field. Somehow, though, we end up calling a function in gen_bitmap64.c which requires that this field be defined.
