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)

Note changing f1 to a non-template, also allows the code to be accepted.

Actually this is rejected in previous versions of GCC via -fchecking=2 option

This one started with r13-6525 and was first fixed on trunk by the
NON_DEPENDENT_EXPR removal r14-4793. The later r14-5531 would have fixed it
too, which I plan to backport to release branches.
