Compile error on windows with assert and -DUSE_XSIMD

[cycomanic]

Here's another compile error on windows with LLVM. This is a bit weird because it only appears with -DUSE_XSIMD and if there are some assert statements (which I thought would be compiled out when specifying -DNDEBUG? but the error still persists).

This code fails:

import numpy as np
#pythran export select_angles(float64[][], int[])
#pythran export select_angles(float32[][], int[])
#pythran export select_angles(float64[][], int32[])
#pythran export select_angles(float32[][], int32[])
def select_angles(angles, idx):
    L = angles.shape[0]
    assert idx.shape[0] >= L
    assert np.max(idx) < angles.shape[-1] 
    anglesn = np.zeros(L, dtype=angles.dtype)
    if angles.shape[0] > 1:
        #omp parallel for
        for i in range(L):
            anglesn[i] = angles[i, idx[i]]
        return anglesn
    else:
        L = idx.shape[0]
        anglesn = np.zeros(L, dtype=angles.dtype)
        #omp parallel for
        for i in range(L):
            anglesn[i] = angles[0, idx[i]]
    return anglesn

Compile error only when -DUSE_XSIMD is specified:

I also got these kind of errors and put a comment here https://github.com/serge-sans-paille/pythran/issues/1725#issuecomment-784863115 I don't know if these issue was related
