worker.js onmessage() captured an uncaught exception : runtimeError ：invalid index into function table

i use the `emscripten_set_main_loop_arg` in pthread worker , and run the .wasm multiple times , there is an error ：
`worker.js onmessage() captured an uncaught exception : runtimeError ：invalid index into function table
RuntimeError: invalid index into function table at :wasm-function[200]:0x1adef8
at Object.invokeEntryPoint
at self.onmessage `

i say the same problem in https://github.com/emscripten-core/emscripten/issues/11715 , in the issue , he said ` I guess the solution is to change this code to actually stash the closure and keep it alive in a thread_local storage until emscripten_cancel_main_loop is called` , so how to keep it alive ?
