Strides of array with dimension of 1 are bogus when NPY_RELAXED_STRIDES_DEBUG is set #12172
Description
See #12171 if you don't want to recompile numpy on your system:
export NPY_RELAXED_STRIDES_DEBUG=1
git clean -xdf
python setup develop --no-deps
# This fails
python -c "import numpy as np; assert np.ones((3, 1, 3), dtype='double').strides == (24, 24, 8)"
# This passes
python -c "import sys; import numpy as np; assert np.ones((3, 1, 3), dtype='double').strides == (24, sys.maxsize, 8)"
Numpy/Python version information:
import sys, numpy; print(numpy.__version__, sys.version)
