(running official v3.7.0 msvc10.win64 at default Quality 9, Windows 10, Lenovo
desktop machine with Core I7, 8 cores/16 threads)
No segfault or other problems for me; the code runs fine. I tried it at various
render resolutions, with/without AA, and different Quality settings.
Render_Block_Size at default (32?). Bounding_Threshold=1.
