Thanks for the patch, Julia, and for submitting the contributor form. I have added you too to the "Doc/ACKS.txt" file.

I wonder how you found this...

My PhD student Suman Saha has developed a tool that finds faults in error handling code by checking whether the error handling code within a function is self-consistent. So if one failure branch frees x, and the next one does not, there is a problem, unless x was freed along the way.

A preliminary description of the work is in the following paper:

S. Saha, Julia L. Lawall, G. Muller : “Finding Resource-Release Omission Faults in Linux”, 6th Workshop on Programming Languages and Operating Systems, Cascais, Portugal (2011)

That paper just has results for Linux, but we are working on applying it to other software, including python.
