Compiled module was created by a newer version of the compiler

[j-f1]

With the Tokamak demo, a clean .build/wasm32-unknown-wasi directory, and .swift-version specified as wasm-5.3-SNAPSHOT-2020-07-02-a, I get this error:

I hope that the issue is fixed in c7557be, if the build passes it would be tagged as a new 5.3 snapshot tonight. Let's wait and see.

Haven't seen this reproduced in long time, closing as outdated.
