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 rpm-4.9.1.2-12.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/2012-02-15/rpm-4.9.1.2-12.fc17/ Although the two bugs in the final category ("Returning (PyObject*)NULL without setting an exception") are false positives, I believe that all of the other bugs reported there are true errors. There may of course be other bugs in my checker tool. I submitted patches for these problems to rpm-maint in December 2011; see: http://lists.rpm.org/pipermail/rpm-maint/2011-December/003138.html http://lists.rpm.org/pipermail/rpm-maint/2011-December/003139.html http://lists.rpm.org/pipermail/rpm-maint/2011-December/003145.html http://lists.rpm.org/pipermail/rpm-maint/2011-December/003152.html http://lists.rpm.org/pipermail/rpm-maint/2011-December/003153.html but I'm filing this here to ensure that the fixes make it into Fedora (and eventually RHEL). 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.

This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
The entire patch set is part of rpm >= 4.10, in rawhide since late March, and the worser memleaks got backported to rpm 4.9.x in older Fedoras as well.
