Describing a suggeasted solution without an actual patch is fine. Would you be willing to complete a copyright assignment for contributions to GCC?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89825 --- Comment #1 from Antony Polukhin --- There's a typo in proposed solution: it should be `&& !_Never_empty` in `_Multi_array`.
