I mean it is a bug.

constexpr int f()
{
        auto p(new int[10000]);
        delete p;
        return 4;
}

int main()
{
        constexpr auto w(f());
}

I mean this is UB so it should not compile. However, it compiles on the latest
GCC.

Not detecting this is a series of security vulnerabilities if people using it
at runtime.
