error: template template argument has different template parameters than its corresponding template template parameter

both gcc and msvc compiles it with no error/warning

Use -frelaxed-template-template-args to enable support for the relaxed C++17 template template arguments rule (see http://clang.llvm.org/cxx_status.html#p0522).
