test case

Hi,

attached code works with
clang++ -c -O2 -m64 -pipe u.cxx -DMAKE_CLANG_HAPPY
but not with
clang++ -c -O2 -m64 -pipe u.cxx

u.cxx:40:11: error: unknown type name 'TGenericClassInfo'
   static TGenericClassInfo *GenerateInitInstanceLocal(const ::space::X<int>*)
          ^
u.cxx:42:7: error: no member named 'Shadow' in namespace 'ROOT'
      R__ASSERT(sizeof(::space::X<int>) ==
sizeof(::ROOT::Shadow::space::XlEintgR));
     
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
u.cxx:42:59: note: instantiated from:
      R__ASSERT(sizeof(::space::X<int>) ==
sizeof(::ROOT::Shadow::space::XlEintgR));
                                                  ~~~~~~~~^
u.cxx:43:22: error: no type named 'TGenericClassInfo' in namespace 'ROOT'
      static ::ROOT::TGenericClassInfo instance;
             ~~~~~~~~^
u.cxx:46:4: error: unknown type name 'TGenericClassInfo'
   TGenericClassInfo *GenerateInitInstance(const ::space::X<int>*)
   ^
4 errors generated.


I (and GCC) think the code is fine...

Cheers, Axel.
