           Summary: noexcept can't reference member data
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: hhinnant at apple.com
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com

Apple clang version 3.0 (trunk 131788) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin10.7.0
Thread model: posix

Here is a minimal test case:

template <class I>
iter_swap(I x, I y) noexcept;

template <class T>
class A
    T t_;
    void swap(A& a) noexcept(noexcept(iter_swap(&t_, &a.t_)));

int main()
    A<int> i, j;

test.cpp:10:56: error: member access into incomplete type 'A<int>'
    void swap(A& a) noexcept(noexcept(iter_swap(&t_, &a.t_)));
test.cpp:15:12: note: in instantiation of template class 'A<int>' requested
    A<int> i, j;
test.cpp:6:7: note: definition of 'A<int>' is not complete until the closing
class A
1 error generated.

The expectation is for this to compile.
