cpdef method w/ unused buffer causes compilation error

[hoytak]

Hello,

The following code segment won't compile:

from numpy cimport ndarray

cdef class DumbClass:
    cpdef dumb_function(self):
        cdef ndarray[int] nothing
        return None

When I try to compile it, it returns

gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -march=i586 -mtune=i686 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -g -fwrapv -fPIC -I/home/hoytak/sysroot/lib/python2.5/site-packages/numpy/core/include -I/usr/include/python2.5 -c cs/test_cpdef.c -o build/temp.linux-i686-2.5/cs/test_cpdef.o -O3 -mtune=core2 -march=core2
cs/test_cpdef.c: In function ‘__pyx_f_2cs_10test_cpdef_9DumbClass_dumb_function’:

cs/test_cpdef.c:408: error: ‘__pyx_bstruct_nothing’ undeclared (first use in this function)
cs/test_cpdef.c:408: error: (Each undeclared identifier is reported only once
cs/test_cpdef.c:408: error: for each function it appears in.)
error: command 'gcc' failed with exit status 1

A quick search shows that pyx_bstruct_nothing is not declared anywhere.

Also, it seems to happen only in class methods and only when cpdef is used (not cdef or def).

I'm using changeset 1374.
