Bug ID: 103865
Summary: virtual function can have a requires clause
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: fchelnokov at gmail dot com
Target Milestone: ---
A virtual function cannot have a requires clause, but GCC allows it to have:
```
struct A {
virtual void foo() {}
};
template<class T>
struct B : A {
void foo() requires true {}
};
int main() {
B<void> b;
}
```
Both Clang and MSVC refuse to accept it. Demo:
