<pre>Consider:
class FriendClass;
namespace inner {
template <typename T> class Cont {
public:
friend class FriendClass;
protected:
explicit Cont(T s) throw() {}
};
}
class FriendClass {
public:
typedef inner::Cont<int> C;
static C foo() throw() { return C(0); }
};
cl.exe builds this fine. Clang complains
hummer:clang thakis$ ~/src/llvm-build/bin/clang-cl /c test.cc
test.cc(15,35) : error: calling a protected constructor of class
'inner::Cont<int>'
static C foo() throw() { return C(0); }
^
test.cc(8,12) : note: declared protected here
explicit Cont(T s) throw() {}
^
1 error generated.
The friend apparently does an unqualified lookup in cl apparently. (This is
reduced from a wrl header used in chromium)</pre>
