With a tentative patch for the gcc PR in place, and this gdb patch:
...
diff --git a/gdb/dwarf2/read.c b/gdb/dwarf2/read.c
index 4910c9b6fc..cf81092691 100644
--- a/gdb/dwarf2/read.c
+++ b/gdb/dwarf2/read.c
@@ -15458,7 +15458,8 @@ process_structure_scope (struct die_info *die, struct
dwarf2_cu *cu)
      these DIEs are identified by the fact that they have no byte_size
      attribute, and a declaration attribute.  */
   if (dwarf2_attr (die, DW_AT_byte_size, cu) != NULL
-      || !die_is_declaration (die, cu))
+      || !die_is_declaration (die, cu)
+      || dwarf2_attr (die, DW_AT_signature, cu) != NULL)
     {
       struct symbol *sym = new_symbol (die, type, cu);

...
we have the expected behaviour.
