Bug ID: 67397
Summary: GCC incorrectly accepts non-type template parameter
pack expansion of a parameter pack declared in the
same template-parameter-list
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: brunocodutra at gmail dot com
Target Milestone: ---
The following is incorrectly accepted by GCC (and clang but not MSVC 14)
template<typename...>
struct foo;
template<typename... t, t... v>
struct foo<std::integral_constant<t, v>...>
{
using type = foo;
};
using bar = foo<std::integral_constant<int, -1>, std::true_type>::type;
[temp.param]/p15:
"A template parameter pack that is a pack expansion shall not expand a
parameter pack declared in the same template-parameter-list."

ICC 2021.3.0 rejects it.
MSVC 19.14+, clang trunk and GCC trunk all accept it
