        <div>
        <pre>When I tried to parse my python script, lldb crashed in
ScriptInterpreterPython::GetDynamicSettings,
lldb\source\Plugins\ScriptInterpreter\Python\ScriptInterpreterPython.cpp on
py_dict.CreateStructuredDictionary().

It is because this function contains a call to PyList_GET_SIZE, which requires
locking the GIL, but locker is already destroyed in scope above.

I use Python 3.6.1.</pre>
