Description
On Bevy, we have run into an issue on nightly where we either get a linker error or invalid bindings with wasm-bindgen.
Linker error on native
Compiling bug_wasm-bindgen_env v0.1.0 (/home/tim/dev/bug_wasm-bindgen_env)
error: linking with `clang` failed: exit status: 1

clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: could not compile `bug_wasm-bindgen_env` (bin "bug_wasm-bindgen_env") due to 1 previous error
Invalid bindings created by wasm-bindgen:
import * as __wbg_star0 from 'env';So it's trying to import from an env package that doesn't exist.
I cannot reproduce the issue on beta or stable toolchains, not sure if this indicates a bug in the compiler.
We discovered that nightly 2025-05-14 still works, hopefully that helps to track down the issue.
To reproduce, see this repository: https://github.com/TimJentzsch/bug_wasm-bindgen_env
It includes scripts to reproduce the error.
I tried to minimize it as much as I could.
