            Bug ID: 255103
           Summary: Out Of Memory with shared true on iOS 16.4
           Product: WebKit
           Version: Safari 16
          Hardware: iPhone / iPad
                OS: iOS 16
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebAssembly
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: serebniti at gmail.com

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.
