Consider the following: struct some_struct { some_struct() = default; some_struct(int v) {} }; typedef union { int x; some_struct y; } a_union_t; a_union_t z; This creates a DW_TAG_typedef with children. I propose to extend the candidate patch to unions: --- gcc/dwarf2out.c 2011-09-15 12:16:36.000000000 +0200 +++ gcc/dwarf2out.c 2011-10-10 13:56:09.000000000 +0200 @@ -8106,7 +8106,7 @@ strip_naming_typedef (tree type, dw_die_ref type_die) { if (type - && TREE_CODE (type) == RECORD_TYPE + && ( TREE_CODE (type) == RECORD_TYPE || TREE_CODE (type) == UNION_TYPE ) && type_die && type_die->die_tag == DW_TAG_typedef && is_naming_typedef_decl (TYPE_NAME (type)))
