wasm-opt fails to optimize

[mohe2015]

Problem

This is probably not fully actionable but maybe it's good that you are aware of the issue. For my own project (see below) wasm-opt fails to optimize. The build shows the following:
ERROR wasm-opt failed with status code exit status: 1:

Steps To Reproduce

Steps to reproduce the behavior:

• Compile https://github.com/tucant/tucant/tree/03c63e32e7b4a44662ff8e3457d366f8cf4517fc using dx build --release with current main of dioxus. Note that I depend on a fork of dioxus in the project so this may theoretically have some effect though I don't believe so.

Expected behavior

Compilation should succeed and produce working output.

Environment:

• Dioxus version: main
• Rust version: 1.87.0
• OS info: Fedora
• App platform: web

Questionnaire

I'm interested in fixing this myself but don't know where to start.

#4313 improves the handling of that error. It then shows:

ERROR wasm-opt failed with status code exit status: 1
stderr: 
stdout: debug_loc error

Setting --keep-debug=false for wasm-bindgen is a workaround.

With dx build --release --features direct I get

stdout: compile unit size was incorrect (this may be an unsupported version of DWARF)

So maybe we should remove dwarf information before calling wasm-opt? Their README does not recommend using DWARF.

data point - wasm opt fails for me on dx bundle --release when release profile in Cargo toml includes strip = false but not otherwise in my experiments so far .. but with stripping happening, I get the below happening
