In this repository, you will find a simple Visual C++ program:
constexpr float foo(size_t itemCount) {
return ( 10 - 4.0f * ( itemCount - 1 ) ) / float ( itemCount );
}
int main() {
constexpr float a = foo(3);
const float & b = foo(3);
printf( "%g %g", a, b );
}
It shall print 0.666667 0.666667, but if it is compiled in Visual Studio 2022 version 17.6 the result is weird: 0.666667 1.
