--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced much further (still has includes):
```
#include <limits>
#include <algorithm>
void f(const char*);
typedef char CharT;
void read(unsigned u)
{
CharT buf[std::numeric_limits<unsigned>::digits10+2u] = {};
CharT* e = buf;
do
{
*e++ = static_cast<CharT>(CharT(u % 10) + CharT{'0'});
u /= 10;
} while (u > 0);
e[0] = 0;
std::reverse(buf, e);
f(buf);
}
```
Just compile with `-std=c++20 -O3 -march=skylake` is enough to get the warning.
