Hi,
this problem here seems to be that is_cxx returns true and at the same
time auto_die and decltype_auto_die is not initialized. Here die==NULL
and we end up calling add_type_attribute for random reasons.
I am testing the following but I am not sure it is proper fix. Are
we supposed to handle auto dies here somehow?
