Would this be responsible for the issue with -fwasm-exception that affected our codebase in iOS 18.0? I reported more details here on the emscripten github: https://github.com/emscripten-core/emscripten/issues/24600 Emscripten are willing to explore adding a workaround if it's possible to avoid triggering this bug, but will likely need some more input from the webkit team about the specific triggers and whether a workaround would be possible. Thanks

This issue and fix are only relevant for 32-bit platforms and this code has never been on by default on them in any case. So unfortunately the answer to your question would be "no".
