System Information
WINDOWS
Operating system: Windows-10-10.0.17763 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 417.22

MAC
Operating system: Darwin-17.7.0-x86_64-i386-64bit 64 Bits

LINUX
Forgot to write down but latest ubuntu with git build from this morning

Blender Version
Broken: version: 2.80 (sub 71), branch: master, commit date: 2019-05-20 16:16, hash: 9efe117535
Worked: (optional) : not sure ... I had a version from 5 days ago, also crashing

Short description of error
Blender crashes when entering edit mode on an object that has both a modified(edited) particle hairs and a material with a texture image slot
See attached file.

Notes:
Only crashes with image texture, other texture types (nosie voronoi, env) seem unaffected
when one removes the Image Texture node, it still crashes. As if by adding Image Texture node it writes some data somewhere.
also seems to be a combination of particles edit, image texture, cycles and editmode.
Crashes on Win, Mac, Linux

Exact steps for others to reproduce the error
Method 1 : Open the attached blend file clean_test.blend
Enable Cycles in the viewport. Enter Edit mode, it should crash

Method 2 : Reproduce from scratch :
Open new default scene with cube
Switch to CYCLES render engine.
Add an Image Texture to the Base Color of the default material (no need to load an image file, just the node is enough).
Add particles system to cube, enable Hair
Enable Cycles Rendered mode in the viewport
Enter Particle edit mode, comb 2-3 hairs
Switch to Edit mode. Should crash
