Bug ID: 52586
Summary: Failure to partially specialize a class when
make_index_sequence is involved
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: vejnar.mar...@gmail.com
CC: blitzrak...@gmail.com, dgre...@apple.com,

The following code fails to compile.
#include <utility>
template <typename T, typename Seq>
struct X;
template <typename T>
struct X<T, std::make_index_sequence<sizeof(T)>> {
};
X<char, std::make_index_sequence<1>> x;
// ^^^
// error: implicit instantiation of undefined template
// 'X<char, std::integer_sequence<unsigned long, 0>>
See https://godbolt.org/z/o8ejrTGKE
Replacing make_index_sequence<1> with the equivalent index_sequence<0> in the
class template definition works around the issue.
