julia 1.4.2, crash with PyPlot and libopenblas-3.7, FreeBSD 12.1

Reproduziere den Absturz auf FreeBSD 12.1 mit Julia 1.4.2, indem du using PyPlot und surf(rand(30,40)) ausführst und anschließend den 3D-Plot drehst. Beginne mit dem Stacktrace bei dgetrf_parallel in libopenblas sowie den NumPy- und PyCall-Frames. Erledigt ist die Aufgabe, wenn die fehlschlagende Abhängigkeit oder Interaktion identifiziert und eine Korrektur oder eine klare Upstream-Diagnose bereitgestellt wurde.

The following happens on FreeBSD 12.1 when I run a PyPlot example and try to rotate the 3D plot:
