<pre>It appears clang has a bug that was once in gcc but has been fixed,
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51184">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51184</a>.
clang compiles the following invalid code (taken from the gcc bug report),
which it shouldn't.
///////////////////////
template<typename T>
struct S{};
struct A
{
virtual void f() = 0;
};
int main()
{
S<A(int)> s;
}
