The following invalid code snippet triggers an ICE since GCC 4.5.0:
========================================
struct A {};
template<typename T> void foo(T t)
{
t.T::~X();
}
void bar()
{
foo(A());
}
========================================
bug.cc: In instantiation of 'void foo(T) [with T = A]':
bug.cc:10:10: required from here
bug.cc:5:3: error: no type named 'X' in 'struct A'
t.T::~X();
