So it sounds like the friend declaration injects 'test' into N and thus 'test'
is found but overload resolution fails.  Whether that injection is correct or
not I don't know.  But given you can even define the function there it is
probably what is specified (C++11 11.3/6).

So I think this bug is invalud.

This is not what is specified, because C++11 7.3.1.2/3 states that such friend
functions can't be found by name lookup unless it's ADL.

Note that the friend 'test' incorrectly hides the global 'test' only if there
are at least 2 friends with that name defined. With only one friend 'test' the
code is compiled correctly.

Also, Clang and ICC compile the code with the expected result.

Note that this has been fixed in gcc-trunk (tested 22-Aug-2015)
