Regression in 0.27.1

[stefanmh]

The following testcase:

a.pxd

import cython
from cpython cimport array

cdef class A:
	@cython.locals(x='double[:]')
	cpdef f(self)

a.py

import array

class A():
	def f(self):
		a = array.array('d', [0.0])

Works in 0.27.0

$ pip install -U cython==0.27.0
$ rm a.c; cython a.py
$

Fails in 0.27.1

$ pip install -U cython==0.27.1
$ rm a.c; cython a.py

Thanks for the report and the short reproducer.
