Oops, sorry, I have a local patch. Apparently I'm trying to support pointer math the same size as pointers (pointers are 24 bits) as an option for the future, which lowers the priority for this bug, but I'd appreciate it if it worked anyway - I'm getting requests for this functionality. By default, pointers are 24 bits but size_t is only 16, which causes wrong-code in some cases.
