Crash when rendering in (hair) Particle edit mode
Closed, DuplicatePublic

Description

System Information
Operating system: Linux-4.15.0-54-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 980/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 396.54

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-11 13:50, hash: rB06312c6d2db8

How to reproduce:
Open blender, add hair particle system to the cube, go to particle edit mode, F12 render -> crash

Note: Doing the same but using the normal particle system will not lead to a crash
