Will it ever get fixed or is it simply > ignored? Unfortunately, there is a limited number of devs and a lot of bugs to fix. Re-reporting bugs helps no-one, since now we have to waste time closing the duplicates, so less time to fix bugs. UNCONFIRMED just means that no dev had the time or interest to look up in the C++ standard whether this is really a bug.

--- Comment #1 from Richard Biener ---
So the actual bug is that the following is rejected:
namespace Foo
{
class Foo
{
public:
static int x;
};
int Foo::x;
}
int main()
{
using namespace Foo;
Foo::x;
return 0;
}
which means that GCC does not consider the used namespace Foo when seeing
the qualified name 'Foo::x' (it finds Foo::Foo:x just fine).
When changing the above to
namespace Foo
{
namespace Foo
{
int x;
}
}
int main()
{
using namespace Foo;
Foo::x;
return 0;
}
then we get
t.C: In function ‘int main()’:
t.C:11:3: error: reference to ‘Foo’ is ambiguous
Foo::x;
^
t.C:2:1: note: candidates are: namespace Foo { }
{
^
t.C:4:5: note: namespace Foo::Foo { }
{
^
which means that the actual ambiguity is on 'Foo' (also with your own
testcase)?
