                    SymbolMap.end() && "Symbol must already have been
                    defined in ExecutePostLayoutBinding!", file

The following code when compiled targeting Windows causes an assertion failure
in the compiler:

//=================
//
// Compile command: clang -cc1 -triple x86_64-pc-windows-msvc -emit-obj
-fcxx-exceptions -fexceptions
//
namespace std {
  inline void A( int* C) {}
  inline void B(int* C ) { A( C); }
  class D {
    public:
    int *E;
    void F(int G) { try { B(this->E ); } catch (...) {} }
  };
}
void foo()
{
    std::D v01;
    v01.F(1024);
}
//=================

When using clang (r234143) built using Visual Studio 2013 Update 4 on my
Windows 7 x64 machine, it produces the following assertion failure:
