System Information
Operating system: Windows 10 Pro
Graphics card: EVGA GTX 1070 SC

Blender Version
Broken: 2.80.0 Date: 2018-12-19 16:09 Hash: 1fc75dbbce
(example: 2.79b release)
(example: 2.80, edbf15d3c0, blender2.8, 2018-11-28, as found on the splash screen)
Worked: N/A

Short description of error

In edit mode, selecting Face Orientation from the Overlays drop down causes a crash.CrashReportFiles.zip

Exact steps for others to reproduce the error

Included Files:

Blend file with object I was working on
Photo for image empty
Photo of which vertices I had highlighted while performing the operation causing the crash.

Open .blend file
Load photo of BMW hubcap (wheel72) into image empty
Refer to Capture image to highlight verts.

Note: odd face issue. The face overlap issue occurred after bridging edge loops. The file should load with the appropriate sections highlighted already. Refer to capture image for reference.

Once the object is set up, use the Overlays drop down menu, and select "Face Orientation"
At this point, I experience a crash.

reg. Face Overlap issue: this is just a flipped normal [which can be fixed by making normals consistent (Shift+N)]

regarding the crash: confirmed, checking...

was working Dec5th
is working in objectmode (also when you change to editmode then)
not related to selection (can also have everything unselected)
not related to flipped normals
does not happen when modifiers are not displayed in editmode
modifiers dont have to be generating (can be deforming also)
does not happen when you remove the second material slot (which has nothing associated anyways...)

Crashes here (where MPoly is NULL)
mlt->poly is 0
const MPoly *mp = &rdata->mpoly[mlt->poly];

I assume the most interesting part is that it doesnt crash when you remove the second material slot (makes me think this might even be related to #59656?)

@fclem: mind having a look?
