Bug ID: 108323
Summary: combine does not change the locale name
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: liweifriends at gmail dot com
Target Milestone: ---
for the following code
```
#include <iostream>
#include <locale>
int main()
{
std::locale loc = std::locale()
.combine<std::numpunct<char>>(std::locale("en_US.UTF-8"));
std::cout << loc.name() << '\n';
std::cout << (std::locale() == loc);
}
```
gcc outputs 'C' and '1' (https://godbolt.org/z/q8fT4oqj3), which seems a bug?
Because locale::combine should return a new and nameless locale.
