[LLVMdev] Clang bug?
...but G++ (4.6-Ubuntu and 4.2-Darwin) compiles it fine:
#include <map>
using std::map;
template<typename K>
struct Templ8 {
struct Member {
typename map<K,Member*>::iterator it;
};
typedef typename map<K,Member*>::iterator iterator_type;
};
int main() {
Templ8<int> test;
}
This is the command-line:
clang++ -stdlib=libc++ -std=c++11 main_bug.cpp
If either of the flags are removed (to compile in C++03 mode, or to
use the non-clang standard library), the code compiles. If the
typedef is removed or c...

...d C++ (both C++98 and C++11).
[The difference in whether we accept the original code isn't clang versus
g++, it's libc++ versus libstdc++. Clang with libstdc++ accepted this code.]
There's two separate problems here. One is that given:
typedef typename map<K,Member*>::iterator iterator_type;
libc++'s std::map implementation was using a construct whose semantics
depended on whether 'Member' is a complete type (thus triggering the
instantiation of that type in the middle of instantiating map<K,Member*>,
creating a dependency cycle between the two instantiations). I...

...nt>*&, S<int>*>::value;
But Adam's code:
#include <map>
using std::map;
template<typename K>
struct Templ8 {
struct Member {
typename map<K,Member*>::iterator it;
};
typedef typename map<K,Member*>::iterator iterator_type;
};
int main() {
Templ8<int> test;
}
is not giving a diagnostic (-stdlib=libc++ -std=c++11).
You seem to be saying that Adam's code with tot clang++ -stdlib=libc++ -std=c++11 is giving a diagnostic. So there's a minor mystery here.
