<pre>The code is as follow:
template<typename T>
struct S{};
struct A
{
virtual void f() = 0;
};
int main()
{
S<A(int)> s;
}
An abstract class shall not be used as a function return type, but clang++
accepts the code.
The code comes from a gcc bug report
(<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51184">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51184</a>).
A previous version of gcc also accepts the code, but it is fixed already.</pre>
