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):
