           Summary: Array.push disappeared
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: david.hansen at gmx.net

I'm sorry but i haven't managed to find a simpler (non GTK) test case.  Running
this little program results in the output:

** (jsarray:893): DEBUG: TypeError: Result of expression 'a.push' [undefined]
is not a function.

Note that the eval in the WebView widget does not produce any console messages.

  return str;

  webview  = WEBKIT_WEB_VIEW (webkit_web_view_new ());
  webkit_web_view_execute_script (webview, "a = []; a.push(42);");
  gtk_widget_destroy (GTK_WIDGET (webview));

  jsStr = JSStringCreateWithUTF8CString ("a = []; a.push(42);");
  jsVal = JSEvaluateScript (jsCtx, jsStr, NULL, NULL, 0, &jsExn);

  if (NULL == jsVal)
    jsVal = jsExn;

  str = js_value_to_cstring (jsCtx, jsVal, NULL);
  g_debug ("%s", str);

  return 0;
