[Bug] Unable compile optimized wasm file at old node.js version

[starua]

Version: wasm-opt version 112 (version_112)
Command args: -O4 -g
Node.js Version: v8.9.3

Got this error when calling WebAssembly.Module:

CompileError: WebAssembly.Module(): Compiling wasm function #318:loop failed: Invalid opcode @+122854
    at Object.<anonymous> (<Glue File>:695:20)

Note that upgrade node.js or disable optimize can solve this error.

I am guessing this behavior exists upstream so it might help to test the build from https://github.com/WebAssembly/binaryen and file an issue with them.

The issue could be related to a change in binaryen 111 - by default binaryen now uses the sign-extension and mutable-globals features, which some runtimes might not support.

To test this you can try 2 things:

• pass the --mvp-features flag to wasm-opt, which should turn off these two features
• downgrade to wasm-opt 110

No, neither --mvp-features flag nor downgrade worked.

This is the optimized wasm file with version 110 & --mvp-features flag: binary.zip
