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
