Bug ID: 115820
Summary: Qualified anonymous union is not diagnosed
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: luigighiron at gmail dot com
Target Milestone: ---
The following code is not diagnosed in GCC:
struct foo{
const union{
const int i;
};
};
This is not a valid anonymous union because the declaration does not follow the
form "union { member-specification } ;" as the C++ standard specifies. This
also generates an error with Clang, though not with MSVC which has the same
bug. Volatile qualification has the same issue as const qualification as
present in the example.
