<div>
<pre>The code is as follow:
template<class T, class U> struct A { };
template<class... T, class ... U> void f( A<T,U>...p);
void g() {
f<int>(
A<int,unsigned>(),
A<short,unsigned short>()
);
}
clang++ rejects it:
code0.cpp:5:2: error: no matching function for call to 'f'
f<int>(
^~~~~~
code0.cpp:2:40: note: candidate template ignored: substitution failure :
deduced incomplete pack <int, (no value)> for template parameter 'T'
template<class... T, class ... U> void f( A<T,U>...p);
~ ^
1 error generated.
g++, instead, accepts it. BTW, T shall end up as {int,short}?</pre>
