Bug ID: 15769
Summary: need eager instantiation of default template arguments
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: [email protected]

This is ill-formed (with a required diagnostic):
#include <type_traits>
template<class T>
struct X {
template<class U = typename T::type>
static void foo(int){}
static void foo(...){}
};
int main(){
X<std::enable_if<false>>::foo(0);
}
g++ and EDG reject, clang accepts.
