Bug ID: 113154
Summary: std::views::values not working with rvalue references
to ranges
Product: gcc
Version: 11.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ivan.lazaric.gcc at gmail dot com
Target Milestone: ---
https://godbolt.org/z/a3c4P9sY6
```
#include <ranges>
#include <map>
void fn(){
std::map<int, int> m;
m | std::views::values; // works
std::map<int, int>{} | std::views::values; // does not work
}
```
not an issue in newer versions, checked 13.2 and it worked
came across this by wanting to do:
```
std::map<Keys, Values> produce_map();
std::cout << std::ranges::max(produce_map | std::views::values) << std::endl;
```
options used: -std=c++20 -O3
