Short description of error
I have an object with a Mirror and Subdivision modifier. Both modifiers have Edit Mode and Realtime checked, and the Subdivision modifier has On Cage checked.
If I enable X-Ray display, then select this object and toggle to Edit Mode, Blender crashes immediately if I click anywhere on the object.
The crash only occurs if X-Ray display is enabled while in Edit Mode.
The crash also only occurs if both modifiers are flagged to display in Edit Mode and Realtime, and only if the Subdivision modifier is flagged to display On Cage.
The crash does not occur if I disable GPU Subdivision in Preferences.

2. Go to numpad 1 front view and select monkey.
3. Toggle into Edit Mode, then toggle into X-Ray display.
4. Select all vertices to the left of the YZ-plane and delete them.
5. Add Mirror modifier with default parameters.
6. Add Subdivision Surface modifier and check On Cage.
7. Toggle to Object Mode, then toggle back to Edit Mode.
