Hi, I am working on the release blocker https://bugs.python.org/issue32232. I tried to apply the patch proposed by Matthias Klose and I found that it works on Unix but it fails to build on Windows (probably because circular imports). I tried to add some tests but after some work on the problem and some comments by Ned Deily I am starting to think that the test for this is basically compiling the whole interpreter with static linking of the built-ins and run the whole test suite. This has to be done as a new build target on Travis. I did some experiments with this following: https://wiki.python.org/moin/BuildStatically But I run into multiple linking errors. The Travis build hangs forever and then fails in the best case. Here is an example of what I am talking: https://github.com/pablogsal/cpython/pull/1 In this PR you can see the patch and the static linking configured as per above and the Travis output. I am happy to work on this as long as someone can tell me what is the appropriate course of action. Thank you very much for your time!
