908464731 MDU6SXNzdWU5MDg0NjQ3MzE= 5424 Bottleneck bug with unusual strides - causes segfault or wrong number 3801015 closed 0     4 2021-06-01T16:13:12Z 2021-08-12T14:41:33Z 2021-08-12T14:41:33Z CONTRIBUTOR      

python import numpy as np import xarray as xr data = np.zeros((1,500, 2)).transpose(1,2,0) xarr = xr.DataArray(data, coords=[('A', range(500)), ('B', [0,1]), ('C', [0])]) xarr.max() The above either returns a very large non-zero number or segfaults. Due to https://github.com/pydata/bottleneck/issues/381.

Dual posting here in case this isn't able to get quickly fixed in bottleneck, as this is a pretty severe bug - especially on the occaions it returns the wrong number rather than segfaulting.
