[Bug c++/35734] New: [4.3/4.4 regression] ICE with copy constructor in derived class

[reichelt at gcc dot gnu dot org]

The following valid code snippet triggers an ICE since GCC 4.3.0
when compiled with "-W":

=========================================
struct A
{
  A();
  template<typename T> A(const T&);
};

struct B : A
{
  B(const B&) {}
};
=========================================

bug.cc: In copy constructor 'B::B(const B&)':
bug.cc:9: internal compiler error: tree check: expected function_decl, have
template_decl in type_has_user_nondefault_constructor, at cp/class.c:4063
Please submit a full bug report, [etc.]

In earlier versions we issued the warning:
bug.cc: In copy constructor 'B::B(const B&)':
bug.cc:9: warning: base class 'struct A' should be explicitly initialized in
the copy constructor
