[Bug middle-end/45171] Invalid DWARF...DIE 0x00006a1d has multiple AT_byte_size attributes.

------- Comment #10 from rth at gcc dot gnu dot org  2010-08-04 19:33 -------
Verified with

  typedef struct { int a, b; } x;

./cc1plus -g -fno-eliminate-unused-debug-types -dA z.c

        .uleb128 0x2    # (DIE (0x2d) DW_TAG_structure_type)
        .byte   0x8     # DW_AT_byte_size
        .byte   0x1     # DW_AT_decl_file (z.c)
        .byte   0x3     # DW_AT_decl_line
        .byte   0x8     # DW_AT_byte_size
        .byte   0x1     # DW_AT_decl_file (z.c)
        .byte   0x3     # DW_AT_decl_line

Note that both byte_size and and the decl location are replicated.
This happens with the C++ compiler, but not the C compiler.
