Description Dave Malcolm 2012-02-16 07:34:04 EST
Description of problem:
I've been writing an experimental static analysis tool to detect bugs commonly occurring within C Python extension modules:

I ran the latest version of the tool (in git master; post 0.9) on
bluefish-2.2.1-2.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):

I manually inspected the results, and the two memory leaks in "Reference leaks" appear to be geunine bugs:
  zencoding.c:zencoding_run_action:ob_refcnt of '*ptr' is 1 too high
(memory leak in error handling)

  zeneditor-interface.c:get_caret_placeholder:ob_refcnt of '*pcaret_placeholder' is 1 too high
(memory leak under normal operation, I think)

The other reported errors seem to be unlikely to happen in practice.

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.

Version-Release number of selected component (if applicable):
gcc-python-plugin post-0.9 git 073d390de53ef52136bd90e5ac06f1ef833d047d running the checker in an *f16* chroot
