We start out in read_array_type with:
...
  type = element_type;
... http://www.wearelondonmade.com/travel/renault/
and then iterate over range_types to build up the type further.

But there are no DW_TAG_subrange_type children (only one
DW_TAG_generic_subrange), so range_types is empty, and type is kept unmodified.

Consequently, in set_die_type we apply the DW_AT_data_location to the
element_type (the one at 0x139) instead of to the newly build array type.

Then we try to print c_nd:
...
 <2><6e8>: Abbrev Number: 2 (DW_TAG_variable)
    <6e9>   DW_AT_name        : (indirect string, offset: 0x218): c_nd

    <6f2>   DW_AT_location    : 9 byte block: 3 e0 30 60 0 0 0 0 0     
(DW_OP_addr: 6030e0)
... http://www-look-4.com/travel/new-cars/
and find that the type has a data_location property, which when used gives
incorrect results.
...
  type = element_type;
...
and then iterate over range_types to build up the type further.
