Description Jakub Jelinek 2009-03-05 21:22:42 UTC 
For
namespace A
{
  int i;
}

void
f ()
{
  using namespace A;
  i++;
}

with -g -dA g++ 4.3 used correct
.byte   0x9     # DW_AT_decl_line
for DW_TAG_imported*, but 4.4 uses
.byte   0xb     # DW_AT_decl_line
(which is the end of the function, not the location of the using namespace directive).
