<div>
<pre>The code is as follow:
namespace Name {
template <class T> class Point;
}
using Name::Point;
template <class T> class Point {
public:
Point() {}
protected:
T member;
};
int main(void) {
Name::Point<double> d;
return(0);
}
clang++ rejects the code with error messages:
error: declaration conflicts with target of using declaration already in scope
template <class T> class Point {
error: implicit instantiation of undefined template 'Name::Point<double>'
Name::Point<double> d;
g++ accepts the code. The code comes from a gcc bug report:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=1876">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=1876</a>
Is this a bug in clang++?</pre>
