So, either we need to put these artificial vars into BLOCK_VARS, or find a way to also keep the original non-gimplified expression in TYPE_DOMAIN. -- jakub at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|4.1.3 |--- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34037
