Oops sorry, the entry for malloc isn't really different though:

 <1><afc1>: Abbrev Number: 3 (DW_TAG_subprogram)
     DW_AT_external    : 1      
     DW_AT_name        : (indirect string, offset: 0x6485): malloc      
     DW_AT_decl_file   : 1      
     DW_AT_decl_line   : 1762   
     DW_AT_low_pc      : 0x68250        
     DW_AT_high_pc     : 0x682ff        
     DW_AT_frame_base  : 1 byte block: 57       (DW_OP_reg7)
