ARGS> struct test {}; int main() { test<> a; return 0; } According to N2242 section 3.6, page 7: If a template-parameter of a class template has a default template-argument, each subsequent template-parameter shall either have a default template-argument supplied or be a template parameter pack. If a template-parameter of a class template is a template parameter pack, it must be the last template-parameter. The compiler issues the following error: no default argument for ARGS at line 1 above. -- Summary: Compiling error with variadic template with fixed parameter with default type.
