--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-10-05 12:10:15 UTC --- -fdump-final-insns calls dump_enumerated_decls and that ICEs on the C++ specific trees (ARROW_EXPR etc.) left over in DECL_INITIAL of the FIELD_DECL by the NSDMI support. I wonder if the DECL_INITIAL of the FIELD_DECLs shouldn't be cleared during genericization.
