Ok, Here is how it is implemented now:
 <1><1b1>: Abbrev Number: 2 (DW_TAG_structure_type)
     DW_AT_name        : array_descriptor2      
     DW_AT_byte_size   : 36     
     DW_AT_decl_file   : 1      
     DW_AT_decl_line   : 16     
     DW_AT_sibling     : <20a>  
 <2><1cb>: Abbrev Number: 3 (DW_TAG_member)
     DW_AT_name        : data   
     DW_AT_decl_file   : 1      
     DW_AT_decl_line   : 16     
     DW_AT_type        : <20a>  
     DW_AT_data_member_location: 2 byte block: 23 0     (DW_OP_plus_uconst: 0)
 <2><1da>: Abbrev Number: 3 (DW_TAG_member)
     DW_AT_name        : offset 
     DW_AT_decl_file   : 1      
     DW_AT_decl_line   : 16     
     DW_AT_type        : <20c>  
     DW_AT_data_member_location: 2 byte block: 23 4     (DW_OP_plus_uconst: 4)
 <2><1eb>: Abbrev Number: 3 (DW_TAG_member)
     DW_AT_name        : dtype  
     DW_AT_decl_file   : 1      
     DW_AT_decl_line   : 16     
     DW_AT_type        : <20c>  
     DW_AT_data_member_location: 2 byte block: 23 8     (DW_OP_plus_uconst: 8)
 <2><1fb>: Abbrev Number: 3 (DW_TAG_member)
     DW_AT_name        : dim    
     DW_AT_decl_file   : 1      
     DW_AT_decl_line   : 16     
     DW_AT_type        : <214>  
     DW_AT_data_member_location: 2 byte block: 23 c     (DW_OP_plus_uconst: 12)
 <1><20a>: Abbrev Number: 4 (DW_TAG_pointer_type)
     DW_AT_byte_size   : 4      
 <1><20c>: Abbrev Number: 5 (DW_TAG_base_type)
     DW_AT_byte_size   : 4      
     DW_AT_encoding    : 5      (signed)
     DW_AT_name        : int4   


 Notice, that there is already a member 'data', that is a pointer to user
array. The problem is, that it points to TAG <20a>, that is a pointer with
missing AT type. I think at least, you need is to add type of the user data to
this tag, then debugger can figure out what is the data.
