The following invalid code snippet triggers an ICE since GCC 3.4.0:
=====================================
template<typename T> class A
{
static int i;
friend int T::foo();
};
struct B
{
void foo() { A<B>::i; }
};
=====================================
bug.cc: In instantiation of 'A<B>':
bug.cc:9: instantiated from here
bug.cc:4: error: prototype for 'int B::foo()' does not match any in class 'B'
bug.cc:9: error: candidate is: void B::foo()
bug.cc:4: error: 'int B::foo()' cannot be overloaded
bug.cc:9: error: with 'void B::foo()'
bug.cc: In member function 'void B::foo()':
bug.cc:9: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in template_class_depth,
at cp/pt.c:295
