System Information
Operating system: Darwin-20.2.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 5500M OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.2.13

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2020-12-27 21:45, hash: aa64fd69e7
Worked: 2.91.0

Short description of error
With the attached blend file, if you switch to rendered view, select the bottle cap and then press "/" to enter local view, Blender instantly crashes with a segmentation fault. It might be related to parenting somehow, as the same happened with other objects that were parented to the bottle.

Exact steps for others to reproduce the error
Open attached blend file
Switch viewport to rendered view
Select bottle cap
Press "/" to switch to local view
Blender instantly crashes

The described steps trigger the kernel_assert(index >= 0 && index < width); in ccl_always_inline const T &fetch(int index) for me.
