<pre>This code, bug.cc, clang emits two duplicated error messages
$cat bug.cc
void
foo1
(typename )
{}
typedef int A;
void
foo2
(typename ::A)
{}
$clang++-trunk -c bug.cc
bug.cc:3:11: error: expected a qualified name after 'typename'
(typename )
^
bug.cc:3:11: error: expected a qualified name after 'typename'
2 errors generated.
The function foo2() is compiled well, but foo1() emits the duplicated messages,
so I guess clang might have something wrong with diagnostic information in this
case.
I have tested it in almost all clang versions, and they all have this issue.</pre>
