Summary REGRESSION (iOS 16 beta) WASM crash

Created attachment 461016 [details] Unity project build triggering WASM crash on iOS 16 Testing Unity WebGL builds on iOS 16 beta, all projects above a certain WASM size crash on load. I can make a small project that runs correctly, and add a small amount to the project to trigger the crash. So it does not appear to be WebGL / ANGLE related, but specifically WASM related. It resembles the WASM crash from 15.4 (https://bugs.webkit.org/show_bug.cgi?id=237180), but it's not the same since the work-arounds we used for that issue did not work here. This is a critical ship-stopper issue for Unity, we do not want to be in the situation we were in with iOS 15.4 shipping with the critical failure. I attached a minimal Unity project build that triggers the crash. I tested MacOS Safari Tech Preview 16 and it does not have the crash, so it seems specific to iOS Webkit.

Justin or anyone who worked on Bug 237180 - would it be possible for you to triage this? This sounds like a recent regression and it'll break Unity's content exported to the mobile web. Thanks.

This is very likely the same to bug 242294
