Bug ID: 104055
Summary: Temporary with conteval constructor is ignored
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: ---
Execution of the following program
```
#include <iostream>
int g = 0;
struct A {
~A() { g = 1; }
consteval A() {}
};
int main() {
A{};
std::cout << g;
}
```
prints `0` in GCC. Demo: https://gcc.godbolt.org/z/7xxn67WbM
This means that the destructor of the temporary (which sets g=1) is not called.
