Bug ID: 114311
Summary: wrong "error: ‘this’ is not a constant expression"
with consteval member function
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: carlo at gcc dot gnu.org
Target Milestone: ---
The following snippet:
```
template<int Id>
struct SymbolRef { };
struct Symbol {
int const id_;
consteval Symbol() : id_(1) { }
template<int Id>
consteval operator SymbolRef<Id>() const
{
return SymbolRef<id_>{};
}
};
```
fails with error:
```
source>: In member function 'consteval Symbol::operator SymbolRef<Id>() const':
<source>:12:22: error: '*(const Symbol*)this' is not a constant expression
12 | return SymbolRef<id_>{};
| ^~~
<source>:12:22: note: in template argument for type 'int'
```
Not a regression.
DOES compile with using `this->id_`.
