Bug ID: 82461
Summary: Temporary required for brace-initializing
(non-literal-type) member variable
Product: gcc
Version: 7.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tvb377 at gmx dot de
Target Milestone: ---
class A {
private:
public:
constexpr A() {}
~A() {}
};
class B {
private:
A a;
public:
constexpr B() : a{} {}
// works also with g++ -std=c++17:
// constexpr B() : a() {}
~B() {}
};
When compiling this with -std=c++17 g++ reports:
error: temporary of non-literal type ‘A’ in a constant expression
note: ‘A’ has a non-trivial destructor
With -std=c++11 and 14 g++ accepts this code as do clang 5.0 and MS cl 19.11
