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

Tái hiện lỗi crash trên FreeBSD 12.1 với Julia 1.4.2 bằng cách chạy using PyPlot và surf(rand(30,40)), sau đó xoay biểu đồ 3D. Bắt đầu với stack trace tại dgetrf_parallel trong libopenblas và các frame của NumPy và PyCall. Công việc được xem là hoàn tất khi xác định được dependency hoặc tương tác gây lỗi và cung cấp bản sửa lỗi hoặc chẩn đoán upstream rõ ràng.

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