Regression against g++-4.3 for g++-4.4 on the variable `problem':

g++ (GCC) 4.4.0 20090303 (experimental):
 <1><54>: Abbrev Number: 8 (DW_TAG_subprogram)
    <55>   DW_AT_specification: <0x33>  
    <5a>   DW_AT_inline      : 0        (not inlined)
 <2><72>: Abbrev Number: 11 (DW_TAG_lexical_block)
 <3><73>: Abbrev Number: 12 (DW_TAG_variable)
    <74>   DW_AT_name        : (indirect string, offset: 0x14): problem
    <7a>   DW_AT_type        : <0x85>
(DW_AT_location is not found by any abstract_origin or specificatione etc.)

g++ (GCC) 4.4.0 20090219 (Red Hat 4.4.0-0.21):
 <1><54>: Abbrev Number: 8 (DW_TAG_subprogram)
    <55>   DW_AT_specification: <0x33>
    <5a>   DW_AT_inline      : 0        (not inlined)
 <2><73>: Abbrev Number: 12 (DW_TAG_variable)
    <74>   DW_AT_name        : (indirect string, offset: 0x1a): problem
    <7a>   DW_AT_type        : <0x10b>

it worked before - g++ (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7):
 <1><85>: Abbrev Number: 10 (DW_TAG_subprogram)
    <86>   DW_AT_specification: <0x33>
    <8b>   DW_AT_inline      : 0        (not inlined)
 <2><a3>: Abbrev Number: 13 (DW_TAG_variable)
    <a4>   DW_AT_name        : (indirect string, offset: 0x14): problem
    <aa>   DW_AT_type        : <0x7f>
    <ae>   DW_AT_location    : 9 byte block: 3 8 0 0 0 0 0 0 0  (DW_OP_addr: 8)

-------------------------------------------------------------------------------
extern void f (int *);

class A
{
public:
  A(int i);
};

A::A(int i)
{
  static int *problem = new int(i);
  f (problem);                          
}

void f (int *)
{
}

int
main (void)
{
  A a(42);
  return 0;
}
