Created attachment 475328 [details] import_exnref_global.js Commit version: 9d02067f5de4b0402f58d6c83039e206439a8a8c System: Ubuntu 20.04.6 LTS, x86_64 The following is Wast code that exports and imports a exnref global. ``` ;; import_exnref_global.wast (module (global (export "g") (ref null exn) (ref.null exn)) ) (register "M") (module (import "M" "g" (global (ref null exn))) ) ``` It is valid export and import, so the modules must be instantiated without error. However, when running `import_exnref_global.js`, the equivalent JavaScript file, JavaScriptCore raises runtime error. ``` $ jsc test.js Exception: RuntimeError: Cannot get value of exnref global (evaluating 'new WebAssembly.Instance(mod, imports)') Instance@[native code] instance@test.js:29:34 global code@test.js:40:18 ```
