Maybe this issue is a bug in `GCC 12.1`. I can't reproduce this issue in GCC
with newer versions.
Although the code snippet mentioned above can not compiled by GCC-12 and
GCC-13, but the original code snippet has some subtle differences.
```c++
$ cat test.cpp
#include <iostream>
#include <vector>
void foo(const std::string& s) {
std::cout << "foo with string" << std::endl;
}
void foo(const std::vector<std::string>& v) {
std::cout << "foo with vector string" << std::endl;
}
int main(int argc, char** argv) {
foo({"123","456"});
}
```
I think the following code snippet is more similar to the original snippet.
```c++
#include <iostream>
#include <string_view>
#include <vector>
std::string_view prefix_1 = "prefix_1";
std::string_view prefix_2 = "prefix_2";
void foo(const std::string& s) {
std::cout << "foo with string" << std::endl;
}
void foo(const std::vector<std::string>& v) {
std::cout << "foo with vector string" << std::endl;
}
void test(const std::string& suffix) {
foo({prefix_1.data() + suffix, prefix_2.data() + suffix});
}
int main(int argc, char** argv) {
test("test");
return 0;
}
```
The above code snippet can be compiled by GCC-12 (12.3.0) and GCC-13
(13.1.0) in Docker environments (ubuntu:22.04 and ubuntu:23.04).
