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.
