             Bug #: 12123
           Summary: clang incorrectly computes mangling/linkage for lambda
                    inside typeid
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Testcase:

#include <typeinfo>
struct A { virtual ~A(); } g;
struct B {
  void f(const std::type_info& x = typeid([]()->A& { return g; }()));
  void h();
};
void B::h() { f(); }

We currently mangle the lambda as "_ZNK1B3$_0clEv"; it should mangle as
"_ZZN1B1fERK1AEd_NKUlvE_clEv".
