Thanks for reporting the bug. I verified, that it is present in
0.14.1+, but in the latest git master (upstream) b1adce4, it works
again.

So I assume it was already fixed upstream. What exactly is "def degree
= 1.0" supposed to do? I know what this does:

cdef double degree = 1.0

But that is something different (I assume).
