Assertion `list_empty(&rt->gc_obj_list)' failed at quickjs.c:1963

[hongxuchen]

When feeding qjs with some crafted javascript files, it may trigger assertion failure at quickjs.c:1963 assert(list_empty(&rt->gc_obj_list)). A sample code snippet is like:

import * as os from "os"; 
var w = new os.Worker()
e = w.onmessage = function() { w }
