--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is by designed and is even documented:
https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gcc/Warning-Options.html#index-Wvla-larger-than_003d
-Wvla-larger-than=‘PTRDIFF_MAX’ is enabled by default but is typically only
effective when -ftree-vrp is active (default for -O2 and above).
