[Cython] Cython compiler crash in 0.24
Hi, When cythonizing a .pyx I get an error in Cython 0.24 which was not there in Cython 0.23.3 After printing the stacktrace, this seems to be because of this line https://github.com/cython/cython/commit/6d55fd189f6ee9d4374d00b8c9c320bd04332bab#diff-28c66ef9e2ff564619ef82aa9d72ee7dR2762 where a None object is passed and the following line calls the None object. https://github.com/cython/cython/blob/6d55fd189f6ee9d4374d00b8c9c320bd04332bab/Cython/Compiler/ExprNodes.py#L1780 Let me know if you need more information.

Re: [Cython] Cython infrastructure
FYI, travis does support CPython dev versions. https://docs.travis-ci.com/user/languages/python#Choosing-Python-versions-to-test-against Travis supports caching of build dependencies. (I remember it was not free on OS X, but it might be now). https://docs.travis-ci.com/user/caching/ Sage is a bit tricky. If there are binaries of Sage develop branch built for Ubuntu 12.04 or 14.04 built by Sagebots hosted somewhere, then you can use it on Travis. I use a Sage release binary to test a project and haven't had any issues with it.
