The following invalid code snippet causes an ICE since GCC 3.4.0:
============================================
template<int> struct A {};
template<int N> struct B : A<N>
{
using A<N>::operator typename A::X;
};
B<0> b;
============================================
bug.cc: In instantiation of 'B<0>':
bug.cc:8: instantiated from here
bug.cc:5: error: no type named 'X' in 'struct A<0>'
bug.cc:5: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in mangle_conv_op_name_for_type, at cp/mangle.c:2826
