> Hi,
>
> It seems that Safari/Safari mobile is supporting WebAssembly but with
> limitations, which make it harder to tell the user whether they can play
> the game or not, so they get cryptic errors instead.
>
> I eventually got a few proper traces from a Safari Mobile user (I don't
> own apple hardware):
>
> For https://renpy.beuc.net/play/?game=the_question.zip:
>   wasm instantiation failed!
>   Error: Out of executable memory in function at index 15855
> (even with freeing memory / restarting the browser)
>
> For the lighter https://www.beuc.net/python-emscripten/demo/
>   exception thrown: RangeError: Maximum call stack size exceeded.,
>   <?>.wasm-function[705]@[wasm code]
>   ... [76 other wasm-function's]
>   <?>.wasm-function[5481]@[wasm code]

> This is the only browser where this happens.
>
> Do you have similar issues with Safari?
> Is there a way to properly detect such limited WebAssembly environment?
> (I wouldn't want to blindly blacklist Safari)

> Cheers!
