Bug ID: 116967
Summary: Accepts-invalid missing constinit specifier on
initializing declaration
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: janschultke at googlemail dot com
Target Milestone: ---
extern constinit int x;
int x;
This TU violates https://eel.is/c++draft/dcl.constinit#1.sentence-2:
> If the [constinit] specifier is applied to any declaration of a variable,
> it shall be applied to the initializing declaration.
However, GCC accepts this program with no warnings:
https://godbolt.org/z/9naoPWKnq (unlike Clang and MSVC, which warn and error,
respectively)
