This is is not a GCC bug, this is a display issue in readelf --debug-dump=info.
This is a display issue specfic to GNU binutils.
If I compile the example with GCC 15 and run it through readelf
--debug-dump=info, I get
<1><49f2>: Abbrev Number: 102 (DW_TAG_variable)
<49f3> DW_AT_name : (string) s
<49f5> DW_AT_decl_file : (data1) 1
<49f6> DW_AT_decl_line : (data1) 2
<49f7> DW_AT_decl_column : (data1) 13
<49f8> DW_AT_linkage_name: (strp) (offset: 0x5830): _Z1sB5cxx11
<49fc> DW_AT_type : (ref4) <0x315a>, string, basic_string<char,
std::char_traits<char>, std::allocator<char> >
DW_AT_type points to a typedef which has name string, but is a child of the
namespace DIE with name std, the debug information is correct.
If you use elfutils readelf instead of binutils readelf, the output is
[ 49f2] variable abbrev: 102
name (string) "s"
decl_file (data1) string.cpp (1)
decl_line (data1) 2
decl_column (data1) 13
linkage_name (strp) "_Z1sB5cxx11"
type (ref4) [ 315a]
external (flag_present) yes
location (exprloc)
it won't show an incomplete name for the typedef.
