EEVEE: Dot Product of two objects' "object" texture coordinate results in crash

Description

System Information
Operating system: Darwin-17.6.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 560 OpenGL Engine ATI Technologies Inc. 4.1 ATI-1.66.42

Blender Version
Broken: version: 2.80 (sub 53), branch: blender2.7, commit date: 2019-03-31 21:52, hash: rBb936d7b16c62
Worked: N/A (new feature)

Short description of error
Plugging the value output of the dot-product node results in a crash if the vectors are from two different objects. This bug seems to occur for any two vectors from different objects, on any vector math operation. I tried using the Geometry node, too, which resulted in a crash.
Not sure if this is a bug or merely an incomplete feature.

Exact steps for others to reproduce the error

bug_VectorMath_000.blend598 KBDownload

From the .blend file attached, simply plug the vector math node into the output (The bug will also occur if you use an emission shader, but it's unnecessary).

I want to add: this is a great feature, and I'm so happy to see it coming to EEVEE! I imagine that, coupled with animationn nodes, EEVEE will be the renderer of choice for VFX artists. Also, as an NPR artist, it's an invaluable tool for me! I want to say a big thank-you to Clément Foucault for all his hard work on EEVEE.

This is related to commit: rBdec9c7d87e5b.
Also, let me know if it is helpful to mention the commit/bug if I know the root cause. I usually don't, so I can see how that could be annoying if I was wrong. Let me know! I want to provide good bug reports.

The bug report is fine as it is.

However, I can't reproduce the crash on my end. The version you are using is quite old by now. Can you see if you still have this issue with the latest build?

I can't reproduce this on Linux with the 8 Apr build.

I'm getting the same bug with 2019-04-08 21:54
Hash: 2a79e3463230

I think it might be a GPU thing-- in User Preferences, there is no GPU available for CUDA or OpenCL.
When I get home I can test this on Windows.
