System Information
Operating system: Windows 10
Graphics card: NVIDIA GeForce RTX 2080
(I also tested on my laptop with a worse graphics card, same issue happened so I've deemed the system to not be the issue)

Blender Version
Broken: 3.1.0 (commit c77597cd0e15?)

Short description and steps to reproduce the error
Crash on select in Edit Mode, with X-Ray on, Subdiv Surface Modifier (with On Cage), and Mirror Modifier

Steps to Reproduce

Open Blender
Delete default objects (camera, light, cube) to have an empty scene (I could also reproduce the bug with this scene by applying things on the cube, but the simpler the better)
Shift-A -> Mesh -> Plane (to create new object)
Add modifier -> Mirror
Add modifier -> Subdivision Surface
Activate "OnCage" for Subdivision Surface modifier
Go to Edit Mode (Tab)
Activate X-Ray (Alt-Z)
Click anywhere in the view, and see Blender closing without warning/error.

Note that Blender was not crashing in any of these instances:

Mirror modifier is after Subdivision Surface modifier
OnCage was not activated for Subdivision Surface modifier
I was in Object Mode
X-Ray was disabled

I saved a simple project, if I try to click in the view after opening it, Blender will crash. But right after I saved it (as new project), it was not crashing (it did once I re-opened it, or when I simply hit Ctrl-S).

Thanks for the detailed report. But I cannot reproduce this issue.

This problem must be related to the GPU subdivision that was recently implemented.
Please try disabling GPU subdivision in {nav Edit > Preferences > Viewport > Subdvision > GPU Subdvision}.

Also try the latest daily build in https://builder.blender.org/download/

Hello,
Thanks a lot for the hint, disabling GPU subdivision indeed fixed the issue, and re-enabling it makes it come back!!
Marking the issue as solved, feel free to re-open it if you want to investigate further why that is the case.

Have a nice weekend!
