From: "nikolay at etnus dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug debug/19954] New: Compiler emits incomplete structure type Date: Mon, 14 Feb 2005 20:42:00 -0000 [thread overview] Message-ID: <20050214181126.19954.nikolay@etnus.com> (raw) This is a readelf output of test program. The variable in question is Derived1 d1; <0><9dd>: Abbrev Number: 1 (DW_TAG_compile_unit) DW_AT_stmt_list : 492 DW_AT_producer : GNU C++ 3.4.3 DW_AT_language : 4 (C++) DW_AT_name : ../../src/tx_basic_class.cxx <3><a86>: Abbrev Number: 4 (DW_TAG_variable) DW_AT_name : d1 DW_AT_decl_file : 1 DW_AT_decl_line : 4 DW_AT_type : <ad5> DW_AT_location : 2 byte block: 91 68 (DW_OP_fbreg: -24; ) <1><ad5>: Abbrev Number: 6 (DW_TAG_structure_type) DW_AT_sibling : <b06> DW_AT_name : Derived1 DW_AT_declaration : 1 ^^^^^^^^^ But there is no defining declaration of this class other than in different CU: <0><ef7>: Abbrev Number: 1 (DW_TAG_compile_unit) DW_AT_stmt_list : 1016 DW_AT_producer : GNU C++ 3.4.3 DW_AT_language : 4 (C++) DW_AT_name : ../../src/Derived1.cxx <1><f76>: Abbrev Number: 2 (DW_TAG_structure_type) DW_AT_sibling : <10b6> DW_AT_name : (indirect string, offset: 0x6ba): Derived1 DW_AT_byte_size : 16 DW_AT_decl_file : 2 DW_AT_decl_line : 5 DW_AT_containing_type: <11c4> But this is clearly wrong, because this declaration have no connection with previous one exept for the name. And in more complex examples it just plain wrong and is not working.
