Description Alex Bor 2023-04-06 11:18:42 PDT 
We update iPhone from iOS 16.2 to 16.4 and get "Out Of Memory" in the console from code that was working before. We have localized the problem.

Try to put this part of code in safari iOS 16.4 console to reproduce:


      wasmMemory = new WebAssembly.Memory({
                          "initial": 205520896 / 65536,
                          "maximum": 2147483648 / 65536,
                          "shared": true
                      });

You will get "Out Of memory".

Now to set  "shared": false and WebAssembly object will be created.
