0.2.86->0.2.87 introduces a coredump in wasm-opt that continues to latest released version

[gilescope]

Describe the Bug

On an arm based m3 mac (and in docker as amd86), versions above 0.2.86 lead to a core dump in wasm-opt.

Smoking PR is likely this one: #3463

Steps to Reproduce

At least the code is open source to reproduce this one:

1. git clone https://github.com/gilescope/dotsamaworld.git
2. git checkout aaa62e360b641c0ebac4ccfac3de60b69be664fc
3. bump wasm-bindgen to > 0.2.86 in Cargo.toml
4. trunk build --release ( https://trunkrs.dev/ )
5. See error:

2024-09-21T19:50:57.044057Z  INFO calling wasm-opt
2024-09-21T19:50:58.448578Z ERROR ❌ error

Caused by:
    0: HTML build pipeline failed (2 errors), showing first
    1: error from asset pipeline
    2: wasm-opt call to executable '/Users/gilescope/.cargo/bin/wasm-opt' with args: '["--output=/Users/gilescope/git/dotsamaworld/target/wasm-opt/release/app-25b623b3922d6169_bg.wasm", "-Oz", "/Users/gilescope/git/dotsamaworld/dist/.stage/app-25b623b3922d6169_bg.wasm"]' returned a bad status: signal: 11 (SIGSEGV)
Error: error from build pipeline

Expected Behavior

should compile cleanly and optimise wasm cleanly.

Actual Behavior

segmentation fault  /Users/gilescope/.cargo/bin/wasm-opt  -Oz

Additional Context

wasm-opt version 116 (version_116) (same for versions back to 105 that I could easily try)

If >=0.2.87 is using a newer version of wasm-opt then it could well be something in the c/c++ of wasm opt project where the problem is rather than here.

[gilescope]

First question is can anyone reproduce it?

[gilescope]

I tried reverting #3463 on top of master but it didn't seem to be the cause. If not that I'm not sure what's causing it. (underlying problem is that wasm-opt isn't written in rust!)

[daxpedda]

Considering the segfault, this looks like a problem in wasm-opt to me rather then in wasm-bindgen.

It might of course turn out that there is some faulty output coming from wasm-bindgen, but that would be hard to investigate without even a proper error message.
