Error when using 13.6

Description:

When trying to use cupy, the below error appears.

It says “This is likely a bug in CuPy” but I feel like it looks more like a compile bug.

Additional info:

• package version(s): 13.6.0-1
• config and/or log files: N/A
• link to upstream bug report, if any: N/A

Steps to reproduce:

>>> import cupy as cu
>>> cu.zeros(100_000) * 2

The above exception was the direct cause of the following exception:
