Bug ID: 104490
Summary: Cannot inherit consteval constructor
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: ---
This code
```
struct B {
bool b = true;
consteval B(int) {}
};
struct C : B {
using B::B;
};
static_assert( C{1}.b );
```
looks valid and accepted in Clang and MSVC. But GCC rejects it with the error
```
<source>:7:14: error: 'this' is not a constant expression
7 | using B::B;
| ^
<source>:7:14: error: '<anonymous>' is not a constant expression
```

Also related to PR 104418, the wording on inherit constructors changed between
C++11 and C++17 too.
