I can reproduce the crash on Windows 8.1, 4.5.0 NVIDIA 419.72 (GT 740m)

This log is from a debug build of some days ago, but it also crashes with the latest buildbot one.

I also was not able to reproduce the crash (Windows64/Radeon RX 480).
But I was able to replicate the assert shown in the previous comment.
That assert was added in rB7b356a85 by @Sergey Sharybin (sergey)

I can't reproduce this either.

@Sergey Sharybin (sergey) can you reproduce this with a nvidia card?

Assigning to self, so it's not lost.
