<div>
<pre>It seems Clang has a bad check for whether the first using-declaration in the
case below introduces a class name or enumeration name that is not a typedef
name.
SOURCE:
int A;
namespace Type { struct A; }
void f5() {
using Type::A;
using ::A;
}
OUTPUT:
cltybad.cc:6:11: error: target of using declaration conflicts with declaration
already in scope
using ::A;
^
cltybad.cc:1:5: note: target of using declaration
int A;
^
cltybad.cc:5:15: note: conflicting declaration
using Type::A;
^
1 error generated.
VERSION INFORMATION:
clang version 3.5
Target: powerpc64-unknown-linux-gnu
Thread model: posix</pre>
