Comment 6 for bug 1263705

I've made a few improvements. Currently, I cannot reproduce crash in function chain nuvola_frame_bridge_execute_script -> JSEvaluateScript -> JSC::evaluate -> ... -> WTFCrash. However, the test suite crashes when JavaScriptCore runs garbage collector:

==12430== Process terminating with default action of signal 11 (SIGSEGV)

I will need to get touch with WebKitGtk/JavaScriptCore developers to help me to find out a cause of this crash and fix the issue.
