--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
There is an alias violation here.
Use -fno-strict-aliasing or as you shown use the correct pointer type
originally.
That is stores to `uint8_t *` and loads from `char *` are considered different
aliasing sets and GCC optimizes based on that.
