Guenter reported that "The problem is seen with gcc 11.3.0, but not with gcc 12.2.0 nor with gcc 10.3.0." https://lore.kernel.org/all/20221227002941.GA2691687@roeck-us.net/ Kees said it's -Warray-bounds, already disabled on gcc 12 for other reasons: https://lore.kernel.org/all/D8BDBF66-E44C-45D4-9758-BAAA4F0C1998@kernel.org/
