The following invalid code snippet triggers an ICE on mainline:
==========================================
template<int> struct A
{
template<typename T> operator T();
};
void foo()
{
A<0>().operator auto();
}
==========================================
bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: tree check: expected function_decl, have
template_decl in build_over_call, at cp/call.c:5123
Please submit a full bug report, [etc.]
