Bug ID: 110999
Summary: GCC rejects static variable with constexpr storage
from inline method definition
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: danakj at orodu dot net
Target Milestone: ---
Godbolt: https://godbolt.org/z/srvhxjqqz
GCC will accept it if the method definition comes after the `constexpr` storage
definition. But it rejects it if the method definition is inline in the class.
```
struct OutOfLine {
static const OutOfLine kConstant;
constexpr int f();
int i = 2;
};
inline constexpr OutOfLine OutOfLine::kConstant;
// Accepted.
constexpr int OutOfLine::f() { return kConstant.i; }
struct InLine {
static const InLine kConstant;
// Rejected.
constexpr int f() { return kConstant.i; }
int i = 2;
};
inline constexpr InLine InLine::kConstant;
int main() {
constexpr int x = OutOfLine().f();
constexpr int y = InLine().f();
}
```
