Description

System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 650/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 419.67

Blender Version
Broken: version: 2.80 (sub 60), branch: blender2.7, commit date: 2019-04-30 22:49, hash: rB480a09a92f7f
Worked: (optional)

Short description of error
Adjusting either colors of a 2 color ColorRamp node to 1.0 value [HSV] cause app crash

Exact steps for others to reproduce the error
Using attached .blend (tried and failed to reproduce in default startup blend).

Blend file opens to Shading workflow with SoundSphere mesh selected, Material SoundSphere

Moderately complex surface shader is work in progress. Centered in screen is newly added ColorRamp node.

Select black color to change. As HSV, change value to 1 by dragging vertical handle or dragging in Value field. Blender crashes before releasing mouse.

Consistent if ColorRamp node is deleted and re-added.

Note: Click & Typing 1 for Value succeeds.

I'm getting asserts when going into HSV mode:

BLI_assert failed: /home/zed/prog/blender/source/blender/depsgraph/intern/depsgraph.cc:120, add_id_node(), at '(id->tag & LIB_TAG_COPIED_ON_WRITE) == 0'

BLI_assert failed: /home/zed/prog/blender/source/blender/depsgraph/intern/builder/deg_builder_relations.cc:1138, build_animdata_curves(), at 'node_from != __null'

If I ignore that I get a crash:

This sounds very similar to T63747.
Someone is passing wrongly ocnfigured scene to the dependency graph. You can't really solve that by ignoring asserts in the code. Those are there for a reason.
