Bug ID: 94967
Summary: std::get<0>(tuple<int> const &&) returns wrong type
Product: gcc
Version: 7.5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rene.r...@fu-berlin.de
Target Milestone: ---
Hi GCC Team,
i couldn't find anything in the advanced search about this but I was wondering
if this is not reported already.
According to the tuple get implementation, the return type of get over a `const
&& tuple` should also be `const &&`. But this fails with gcc 7 but works with
gcc-8,9 and 10.
Here is the link to godbolt: https://godbolt.org/z/akae2V
And this is the offending line that fails
```
#include <tuple>
static_assert(std::is_same<decltype(std::get<0>(std::declval<std::tuple<int>
const &&>())), int const &&>::value);
```
Thank you very much for your support.
