Good point.

I think I know what the problem is:

We never call equate_type_number_to_die_number for the type of array
elements.

You might think that the call in output_array_type_die would handle this,
but if you look closely at the loop in subscripe_data_attribute it can
change TYPE before calling type_attribute for the array element type.
