[Bug c++/16781] New: [3.3 regression] ICE in cxx_scope_find_binding_for_name with missing 'template' disambiguator

["bangerth at dealii dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This is spinoff 1 from PR 16777: this code ICEs 3.3.x, but no other 
compiler (including 3.4 and mainline) 
-------------------- 
struct X { 
    template <typename> void foo(); 
  
    void bar() { 
      this->X::foo<int>(); 
    } 
} 
-------------------- 
 
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc 
x.cc: In member function `void X::bar()': 
x.cc:5: internal compiler error: tree check: expected identifier_node, have  
   baselink in cxx_scope_find_binding_for_name, at cp/decl.c:2384 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
 
One can work around the problem by writing 
  this->X::template foo<int> ();  
 
This was fixed with the new parser in 3.4, so Gaby will have to decide 
if its worth trying to fix it in 3.3.x.
