Bug ID: 102004
Summary: The opaque-enum-declaration whose enum-head-name
contains a nest-name-specifier should be permitted in
an explicit specialization
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: xmh970252187 at gmail dot com
Target Milestone: ---
template<class T>
struct A{
enum C:T;
};
template<>
enum A<int>::C:int;
This explicit specialization should be accepted by comfort implementations.
Since the standard only says that
> If the enum-head-name of an opaque-enum-declaration contains a nested-name-specifier, the declaration shall be an explicit specialization.
Clang accepts this example while GCC rejects it with the diagnosis
"opaque-enum-specifier must use a simple identifier".
