In sipGetThis, there is the code fragment:
if (thisObj != NULL)
{
// sipParseArgs() will decrement the reference count.
Py_INCREF(arg);
return (sipThisType *)thisObj;
}
The comment appears not to be true, and the arg tuple passed to sipParseArgs
never gets gc'ed as a result of the incref. commenting it out fixed the
problem.
