Comment:

 Has duplicates #59383, #59979. Crash logs are attached to #59979.

 The upstream bug report we have been presuming this relates to is
 https://github.com/numpy/numpy/issues/10330. However it is closed because
 it was thought not to be a numpy bug but rather a defect in the Xen
 hypervisor that that user was using. There is a
 [https://github.com/numpy/numpy/issues/10330#issuecomment-355837109 sample
 program] which was reporting that AVX was supported but trying to use AVX
 functions was causing a crash.

 I have tried that test program on our Sierra and High Sierra buildbot
 workers. On both, it reports that AVX is not available. Also, the upstream
 bug report says the problem occurs when doing "simple array additions",
 but in our case, the problem occurs immediately after "import numpy". So
 perhaps our problem is not the same one.

 Our buildbot workers ''are'' virtual machines (running under VMware ESXi
 on Xserves) so that part may still be relevant. If anybody experiences
 this problem on Sierra running directly on a Mac, not in a VM, let us
 know.
