The following valid code snippet triggers an ICE since at least GCC 2.95.3:
=================================
template<int> struct A
{
template<int> struct B
{
template<int> void foo()
{
struct C { C() {} };
}
};
};
=================================
bug.cc: In member function 'void A<<anonymous> >::B<<anonymous> >::foo()':
bug.cc:7: internal compiler error: tree check: expected class 'type', have
'declaration' (function_decl) in push_template_decl_real, at cp/pt.c:3857
Please submit a full bug report, [etc.]
