Looks like this requires my grow_memory patch to fix the test which fixes creating memory w/ initial size of zero.

Hmm, I find this surprising since duplicates aren't useful but are also harmless. I filed a PR in the design repo to add this restriction: https://github.com/WebAssembly/design/pull/932 It seems silly to restrict when overwrite semantics is clear and requires less work. In any case, this is a good PR to follow the spec, a nice corner case, and reversing polarity is easy in the future.
