This might be related:

the following code compiled with gcc version 4.3.0 20080428 (Red Hat 4.3.0-8):

namespace A{
  int x = 1;
}

int main()
{
  namespace B = A;

  return 0;
}

producdes the following debuginfo:

...
 <1><4f>: Abbrev Number: 5 (DW_TAG_subprogram)
    <50>   DW_AT_external    : 1        
    <51>   DW_AT_name        : (indirect string, offset: 0x9): main     
    <55>   DW_AT_decl_file   : 1        
    <56>   DW_AT_decl_line   : 6        
    <57>   DW_AT_type        : <0x6f>   
    <5b>   DW_AT_low_pc      : 0x40055c 
    <63>   DW_AT_high_pc     : 0x400567 
    <6b>   DW_AT_frame_base  : 0x0      (location list)
 <1><6f>: Abbrev Number: 6 (DW_TAG_base_type)
    <70>   DW_AT_byte_size   : 4        
    <71>   DW_AT_encoding    : 5        (signed)
    <72>   DW_AT_name        : int      
 <1><76>: Abbrev Number: 4 (DW_TAG_imported_declaration)
    <77>   DW_AT_name        : B        
    <79>   DW_AT_decl_file   : 1        
    <7a>   DW_AT_decl_line   : 8        
    <7b>   DW_AT_import      : <0x2d>   [Abbrev Number: 2 (DW_TAG_namespace)]
...

the the above die 0x76 should be a child of 0x4f not sibling. Similar nesting
is expected for lexical scopes of course.
