It seems that `cargo wasi` uses an outdated version of `wasm-opt` #49

I was trying to build parts of the rustc using cargo wasi and found that librustc_expand causes wasm-opt to crash.

I filed an issue https://github.com/WebAssembly/binaryen/issues/2821 but it seems that the most recent version does fine.

Any ideas on why this happens?

This updated quite recently, although there has been one more release since then. Is the fix for your issue in that commit range?

0x7CFE commented 4 years ago

Honestly, I don't know. My experience is that wasm-opt compiled form master works, but the one that is executed by cargo wasi v0.1.22 does not.

I assume that the fix was introduced less than 2 weeks ago.

Can you try running the binary releases from binaryen itself? If that doesn't work then this is likely an issue with binaryen's binary releases I think?
