Description of problem: I've been writing an experimental static analysis tool to detect bugs commonly occurring within C Python extension modules: https://fedorahosted.org/gcc-python-plugin/ http://gcc-python-plugin.readthedocs.org/en/latest/cpychecker.html http://fedoraproject.org/wiki/Features/StaticAnalysisOfPythonRefcounts I ran the latest version of the tool (in git master; post 0.9) on python-cups-1.9.60-1.fc17.src.rpm, and it reports various errors. You can see a list of errors here, triaged into categories (from most significant to least significant): http://fedorapeople.org/~dmalcolm/gcc-python-plugin/2012-03-05/python-cups-1.9.60-1.fc17/ I've manually reviewed the issue reported by the tool. Within the category "Reference count too low" the 1 issue reported: cupsmodule.c:cups_require:ob_refcnt of return value is 1 too low appears to be a genuine problem: the: return Py_None; should be a Py_RETURN_NONE; otherwise every call to cups_require() will leak a reference to the Py_None singleton. There may of course be other bugs in my checker tool. Hope this is helpful; let me know if you need help reading the logs that the tool generates - I know that it could use some improvement.
