Bug ID: 83921
Summary: GCC rejects constexpr initialization of empty
aggregate.
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eric at efcs dot ca
Target Milestone: ---
Reproducer:
// g++ -std=c++14
struct Foo {};
constexpr void test() {
Foo f; // error: uninitialized variable 'f' in 'constexpr' function
}
This error is obviously correct for non-empty types, however surely an empty
struct doesn't need an initializer?
If we agree this is a bug, it is a regression from the 6x release series, which
doesn't diagnose this code.
