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-bibtex-1.2.5-4.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/2012-04-03/python-bibtex-1.2.5-4.fc17/ I've manually reviewed the issues reported by the tool. Within the category "Reference leaks" the 2 issues reported appear to be genuine bugs: bibtexmodule.c:bib_reverse:ob_refcnt of '*authobj' is 1 too high: missing Py_XDECREF, I think. bibtexmodule.c:_bib_next:ob_refcnt of '*name' is 1 too high: should use code "N" to Py_BuildValue, not code "O" Within the category "Segfaults within error-handling paths" the 11 issues reported appear to be genuine crashers under low-memory conditions, where a function returns NULL and the code doesn't check for that. Within the category "Returning (PyObject*)NULL without setting an exception" the 5 issues reported appear to be false-positives 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.

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.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora19
The upstream maintainer updated the code to fix issues reported here. So, I'm closing this bug for now. The update comes as python-bibtex-1.2.7-1.fc21 in rawhide.
