#include <iostream>
#include <source_location>

auto g(auto...) {
std::cout << std::source_location::current().column() << "\n";
}

auto f() {
std::cout << std::source_location::current().column() << "\n";
}

int main() {
g();
f();
std::cout << std::source_location::current().column() << "\n";
}

GCC-trunk output 43, 44, and 44, but the first one should be 44.
