c++ – Integer overflow warning only when using const keyword

I’m encountering a warning with the const keyword in C++ when using clang++ v. 17.0.1 or newer, with the flag -Winteger-overflow.
Here’s the code snippet:

int foo_const()
{
    const auto min = std::numeric_limits<int>::min(); // const keyword
    return - min; // warning: overflow in expression; result is -2147483648 with type 'int' [-Winteger-overflow]
}

int foo()
{
    auto min = std::numeric_limits<int>::min();   // no const keyword
    return - min; // no warning
}

In the foo_const function, I’m getting a warning about potential integer overflow. However, the same operation in the non-const foo function compiles without a warning.

I’d appreciate some help understanding why the const keyword triggers the overflow warning in this specific case.
