Bug ID: 124308
Summary: Accepts templated enum declaration
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: suyuchang at whu dot edu.cn
Target Milestone: ---
The code attempts to declare an enum as a template: template <typename...> enum
X1;. Clang rejects the code, while GCC accepts it.
Code:
enum class X1 ;
template < typename ... > enum X1 ;
Command:
clang++ test.cpp
<source>:2:35: error: enumeration cannot be a template
2 | template < typename ... > enum X1 ;
| ^
<source>:2:27: error: declaration does not declare anything
2 | template < typename ... > enum X1 ;
| ^
2 errors generated.

The test case was generated by a fuzzer.
