            Bug ID: 111705
           Summary: [14 Regression] use of concepted copy constructored
                    struct inside a template function messes up
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
```
template<class> concept c = true;
template<class T>
struct ts
{
  template<class T1>
   requires(c<T1>)
    ts(const ts<T1>&);
  template<class T1>
   requires(!c<T1>)
    ts(const ts<T1>&) = delete;
  ts() = default;
};


using P = ts<int>;
void (*f)(P);
template<class>
void f1()
{  
  P x;
  f(x);
}
```
This gets rejected with the following (bogus) error message:
```
<source>: In substitution of 'template<class T1>  requires !(c<T1>)
ts<int>::ts(const ts<T1>&) [with T1 = int]':
<source>:21:5:   required from here
   21 |   f(x);
      |     ^
<source>:10:3:   required by the constraints of 'template<class T>
template<class T1>  requires !(c<T1>) ts<T>::ts(const ts<T1>&)'
<source>:9:12: error: satisfaction value of atomic constraint '!(c<T1>) [with
T1 = int]' changed from '<expression error>' to 'false'
    9 |   requires(!c<T1>)
      |           ~^~~~~~~
<source>:21:5: note: satisfaction value first evaluated to '<expression error>'
from here
   21 |   f(x);
      |     ^
```

This was reduced from PR 111703 (but is different since this was accepted
before  in GCC 13)
