cpdef method w/ no self crashes cython

[robertwb]

Hello,

In version 1474:7f1b96cad687, the following code crashes the compiler:

cdef class A:
    cpdef foo(): 
        pass

Note that foo() should be foo(self). If you replace the cpdef with either def or cdef, the error is correctly reported and cython works fine. With the above code segment, however, we get the following error in addition to the error report:

Error converting Pyrex file to C:
------------------------------------------------------------
...
cdef class A:
    cpdef foo():
         ^
------------------------------------------------------------
