Crash can be repeated with the above configurations. Downloading and installing the required font didn't change the nature of the crash.

I cannot confirm any crash here. However, your custom font is missing from the file, so that may be the culprit - bad fonts can generate bad geometries and our font handling code is not advanced enough to always cope with those correctly, which can lead to crash. So please:

  • Try the latest build from our buildbot.
  • Try using another, more classical and well known font and see if it still crashes.

Oh, did not saw latest comment… so crash can be replicated, and seems to be a Cycles issue, OSX-only maybe?

@Brecht Van Lommel (brecht), @Sergey Sharybin (sergey), will leave it to you. :)

The Blender internal BVH builder is running out of stack space, it might be macOS specific since threads there have a smaller default stack size than other operating systems.
