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-GeoIP-1.2.5-0.4.20090931cvs.fc15.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-GeoIP-1.2.5-0.4.20090931cvs.fc15/ I've manually reviewed the issues reported by the tool. Within the category "Reference leaks" the 2 issues reported appear to be genuine leaks; the error-handling paths appear to need a: Py_DECREF(GeoIP) Within the category "Segfaults within error-handling paths" the 12 issues reported appear to be genuine bugs that could occur under low-memory conditions (where an allocation fails, returning NULL). Within the category "Returning (PyObject*)NULL without setting an exception" the 1 issue reported may or may not be a real bug, depending on whether GeoIP_range_by_ip() sets the thread's exception status when it returns NULL. 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.

Dave, where is the /test.py script referenced in the gcc invocation? I built the latest version of this package into rawhide today. I'd like to see if it fails in a way similar to the bugs you note here, before it gets too far into F19's release process. Perhaps you can re-run your check based on rawhide tomorrow? Thanks, Matt
reported to support.
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
