I ran across a compilation error using 0.24a1. It's actually the same error that I posted to the list a while back (https://groups.google.com/d/msg/cython-users/_ShPVfZAuKA/RxiS0dfRDwAJ), but at the time, I didn't have a minimal working example that had been extracted from a much more complicated project that I couldn't post publicly. I now have a minimal demonstration that I've posted here: https://gist.github.com/synapticarbors/c6268e25ce22e4d04b4d It fails on both OSX and Windows (using mingw) with traceback: $ python setup.py build_ext -i Compiling factors.pyx because it changed.

It compiles without error using Cython 0.22.1, which is what I'm using in production. It looks like a possible codegen error to me since the function call doesn't match the prototype, but it's deep enough in the cython internals that I'll defer to a Cython developer. Any help with this would be very much appreciated. Thanks, Josh
