Bug ID: 105563
Summary: Consteval copy-constructor is allowed in not-constant
expression
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: ---
In the following program, struct A has `consteval` copy-constructor, which is
invoked in main() run-time via A{a1}:
struct A {
int i = 0;
A() {}
consteval A(const A&) = default;
};
int main() {
A a1;
A{a1};
}
Both Clang and MSVC reject this program, but not GCC. Demo:
