Parser throws exception for double* argument of function

[JimKleckner]

The following code:

cdef int doublePointer(double* inOutArray):
    return 1

generates the following error traceback with changeset 1291:16fc9454a2e5

It should generate a meaningful error message.

I am unable to reproduce this, either with 1291 or the most recent hg repo.

[JimKleckner]

Ugh, reduced it too far. Try this bad code:

cdef int foo((double*)inOutArray, ):
    cdef int i
    i = <int> inOutArray
    return i
