--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note, the VAR_DECLs disappear from the local decls during ssa pass, but guess id_string keeps to be referenced from debug info while id_string.55 only from the DECL_VALUE_EXPR. If DECL_VALUE_EXPR is the only table needing two passes (or if there are just a couple), perhaps we might need some new GTY option to request two passes rather than one for those.
