Invalid call to pythranized function `test(float64[:] (reshaped)) for negative strides

[jeanlaroche]

When compiling this simple function:

import numpy as np

#pythran export test(float[] or float[::])
def test(x):
    return x*2

I get an error when calling it with:

A=np.ones(10,dtype=float)
test(A[-1::-1]) #<- error: Invalid call to pythranized function `test(float64[:] (reshaped))'
test(A[0::2])   # works

BTW this seems similar to #1049 which was just closed...

Note: this still does not work with the latest pythran on master. 80e7bbcb0
