Problem

While building release app wasm-opt failed with status code 6.

if execute build process with --debug-symbols=false everything was builded correct.

dx build --release --web --verbose --debug-symbols=false

Hi, I'm getting the same error when I try to upgrade our application to Dioxus 0.7.2:

With previous version 0.7.1 of the dx-cli it worked fine.

Our command line is: dx bundle --web --release

My environment:

• Dioxus: 0.7.2
• Rust version: 1.92.0
• OS: MacOS 26.2 and Linux
• App plattform: web

There seems to be something odd going on with the debug symbols emitted by Dioxus 0.7.2. As a workaround for now, you can disable them by passing the --debug-symbols=false argument to your build commands.

thanks for the workaround!

does the failure result in any further issues? even after having failed wasm-opt my bundles seem to work just fine, could that be the case?
