Created attachment 475261 [details] return_try_table.js Commit version: 9d02067f5de4b0402f58d6c83039e206439a8a8c System: Ubuntu 20.04.6 LTS, x86_64 The following Wasm module contains a function whose body is `return` and `try_table`. ``` ;; return_try_table.wat (module (func (return) (try_table)) ) ``` It is a valid Wasm module, so it must be succeed to parse and validate. However, when running `return_try_table.js`, the equivalent JavaScript file, JavaScriptCore raises compile error. ``` $ jsc return_try_table.js Exception: Error: Wasm validate failure module@return_try_table.js:17:20 global code@return_try_table.js:23:7 --> CompileError: WebAssembly.Module doesn't parse at byte 6: function body size doesn't match the expected size, in function at index 0 ```
