System Information
Windows 10 64bit (Home)
Nvidia GeForce GTX 660 (opengl driver: 4.5.0 NVIDIA 388.13)

Blender Version
Broken: 2.80 (sub 24), hash: be0e58d980

Short description of error
Blender crashes when entering wireframe mode when "single" color is selected in overlay popover. I found steps to crash it in edit mode consistently, but it also happens in object mode sometimes.

Exact steps for others to reproduce the error

Open Blender
Load factory settings
Enter edit mode
Leave edit mode

Repeat the following until crash (usually happens on first try, but not always):

Enter edit mode
Enter wireframe mode (crash happens here)
Enter object mode
Leave edit mode

Can confirm a crash here (linux, 970m with 396.45 drivers)

Is v_first_ofs supposed to be NULL here ? backtrace:

I can't get it to crash on linux + 960m.

v_first_ofs is supposed to be null pretty much every time. it is its default value.
@lichtwerk can you try running with --debug-gpu and also try running with v_first_ofs = NULL all the time.

Hi @fclem!
P786 for the output of --debug-gpu (wall of text!)
P787 for the blender.crash.txt. (incl. op log repo steps)
(not sure these help..)

How would I "try running with v_first_ofs = NULL all the time"?
