  1. fix: block memory allocation overflow 

    this fixes potential overflow bugs in pointer calculation by blocking
memory allocation above a certain size. the size limit is set at
`2**64`, which is the size of addressable memory on physical machines.

practically, for EVM use cases, we could limit at a much smaller number
(like `2**24`), but we want to allow for "exotic" targets which may
allow much more addressable memory.
