System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Radeon RX 570 Series ATI Technologies Inc. 4.5.13596 Core Profile Context 20.5.1 27.20.1017.1011

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-07-26 22:08, hash: ba9c88ce18
Worked: (Crashing ever since the support for direct rendering of sculpt vertex colors)

Short description of error
[It crashes when you add a 2nd layer of sculpt vertex color and use it in the shader editor while rendering]

Exact steps for others to reproduce the error
As demonstrated in the video, open the attached blend file and plug the 2nd vertex color node in the roughness or any other shader attribute

Sculpt Vertex Color Crash.blend

Sculpt Vertex Color Crash.mp4

Even if it does not crash, it spawns artifacts

This seems to be a refresh problem, goes away as soon as I do some strokes on the Color.001 sculpt vertex color layer

Today's build is also crashing when I open a file from 23 july's build that has sculpt vertex colors being used in it (that build also crashes when a 2nd layer is used though, it's just that the file from that build is not rendering in this build at all). It crashes even if you remove all vertex color nodes, parameters or any existing shaders.

If you create a new file in this build, it works fine with just one layer of sculpt vertex colors.

By the way, I love that we now have the ability to render it directly : ) @PabloDobarro

Not getting a crash here, but that second layer seems to be borked in a way:

For me, this goes away as soon as I do some strokes on the Color.001 sculpt vertex color layer

@Zohaib : does it still crash if you actually do some strokes on the Color.001 sculpt vertex color layer?
@PabloDobarro : could it be that there is something wrong when adding a (blank) new sculpt vertex color layer?

@lichtwerk
It crashes when you change the node input while in rendered mode for me. It seems to work fine if you switch the nodes in object mode and then go the rendered mode though. Blank or not, it is crashing if I change it in rendered view. It does lets you paint on and change to more layers inobject mode as I mentioned before.

Update: It only crashes when you switch the nodes while rendering in Eevee. Cycles seems to work fine.

Still cannot reproduce a crash, but confirming since there seems to be a bug in any case.
