[LLVMdev] Clang bug?

Is this a relevant location to provide information about what I
believe is a compiler bug in clang?  If not, please forgive me for
posting it here.  (Perhaps you can redirect me to some place more
appropriate.)  If so, here are the details:

I have a short 15-line C++ program using only one standard header that
clang fails to compile properly under C++11 with the new standard
library (although the code itself doesn't use any C++11-specific
syntax), 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 commented out, clang++ compiles the code fine.
If the typedef is moved inside the "Member" inner class, the code
compiles fine (even if a second typedef pulls the symbol back into the
main template scope).

My clang version information:
    Apple clang version 4.1 (tags/Apple/clang-421.11.65) (based on LLVM 3.1svn)
    Target: x86_64-apple-darwin12.2.0
    Thread model: posix

The error output:

main_bug.cpp:7:34: error: no type named 'iterator' in

[LLVMdev] Clang bug?

I think you should send a mail to cfe-dev at cs.uiuc.edu; clang mailing alias.

For reporting bugs on Clang use the Bugzilla bug reporting service. For
discussing topics related to Clang use the cfe-dev mailing list. Both
are available from http://clang.llvm.org

[LLVMdev] Clang bug?

That is one evil bug!

I just tested it against tip-of-trunk clang and it appears to be fixed there
(just fyi for everyone).

[LLVMdev] Clang bug?

Reduced testcase:

template<typename T> struct A { typedef decltype(T() + 0) type; };
template<typename T> struct B {
  struct C { typedef typename A<C*>::type type; };
  typedef typename A<C*>::type type;
};
B<int> b;

... produces ...

<stdin>:3:38: error: no type named 'type' in
'A<B<int>::C *>'
  struct C { typedef typename A<C*>::type type; };
                     ~~~~~~~~~~~~~~~~^~~~
<stdin>:1:54: note: in instantiation of member class
'B<int>::C' requested
here
template<typename T> struct A { typedef decltype(T() + 0) type; };
                                                     ^
<stdin>:4:20: note: in instantiation of template class
'A<B<int>::C *>'
requested here
  typedef typename A<C*>::type type;
                   ^
<stdin>:6:8: note: in instantiation of template class
'B<int>' requested
here
B<int> b;
       ^

I think it would be worth filing this as a diagnostic QoR issue. We should
be able to say something like

<stdin>:3:38: error: member 'type' of 'A<B<int>::C
*>' required recursively
within the instantiation of 'A<B<int>::C *>', but it has not
been
instantiated yet
