Wasm crashing on iPhone

[Ulhas Pawar]

Hello All!

I am using Emscripten to build Wasm for my application.

I am facing weird issue on iPhones where wasm crashes. Post crash, browser tab is reloaded.

My current setup is on 2.0.15.

Do let me know if I need to build with flags or different Emscripten builds.

Any help is appreciated :)

Thanks,

Ulhas

Is there some reason you are using this old version from 2.5 years ago?  It might be easier for us to fix if you can report a problem that exists with the latest version.

Does the application crash consistently?  Does it ever crash on the desktop safari browser?   It sounds like the entire browser or tab is crashing, is that right? 

cheers,

Note that Safari on iOS is much more memory-constrained than on the desktop, and much more aggressively terminates tabs for high memory usage. This can easily happen when allocating a lot of linear memory for the WebAssembly module, or simply from all the JIT compiled code.

Hello All,

It turned out indeed memory restrictions issue in iPhones.

It works smoothly for smaller images - upto 800-900, but crash for larger ones.

Thanks,

Ulhas
