Hello,
this is a bug report for cython 0.12.1. The bug occurs when a function
argument with default value is named differently in the .pyx and the .pxd
file.
A minimal example is:
foo.pyx contains:
===========================
cpdef test(test=5):
pass
===========================
foo.pxd contains:
===========================
cpdef test(FJKHFKLJDHF=*)
===========================
the traceback is:
/tmp/Cython-0.12.1$ python2.5 cython.py foo.pyx
Traceback (most recent call last):

best regards and thanks a lot for cython, I like it a lot!
