alexcrichton opened PR #9883 from alexcrichton:fix-windows32 to bytecodealliance:main:

This commit fixes the build of the wasmtime crate and CLI on 32-bit Windows. This required adding some extra bits for trap handling and a stub for "unimplemented" for unwind information registration. This then additionally refactored our CI configuration to place all of the cross-compile checks in one matrix instead of spread out across a few jobs.

Closes #9882

pulling wasmtime in transitively and compiling on macos. So possible issue is there.

@alexisvincent I'm having a tough time reproducing that locally and I'm not sure why... Can you share what the dependency directive in Cargo.toml looks like for wasmtime? (unsure which features you have active)

Get it for --target=i686-pc-windows-gnu:

[dependencies.wasmtime]
path = "../../vendor/wasmtime/crates/wasmtime"
default-features = false
features = [
  "runtime"
]

Ill see if I can get a repro

Ah no yep that works, thanks! I tried every combo but that, don't know why I didn't try the most obvious combo to start...
