Short description of error
Blender Crashes on Alembic export when object is using hair particles if simple child particles are being used and "Display" value is set to anything other than 100%

Exact steps for others to reproduce the error

  1. Open Blender
  2. Add particle system to default cube set type to "Hair"
  3. Under the Children menu select "Simple"
  4. Under "Display" drop the slider down to any value under 100%
  5. File > Export > Alembic > press "Export Alembic"
  6. Blender crashes

Event Timeline

At least with the current Buildbot builds Alembic export always crashes as soon as I use "Simple" or "Interpolated" children no matter what I set the "Display" amount to.

Official 2.78c is rock solid and I can't even reproduce this crash here. I can export hair to Alembic all the time even with display amount set to 1.
