Comment 1 H.J. Lu 2006-03-10 20:40:15 UTC 
The problem is

 <2><4ef9>: Abbrev Number: 52 (DW_TAG_inlined_subroutine)
     DW_AT_abstract_origin: <4f18>
     DW_AT_ranges      : 0x3e0
     DW_AT_call_file   : 0
     DW_AT_call_line   : 0

According to DWARF 3, 0 means no source file has been specified. The same
applies to DW_AT_call_line.
