------- Comment #12 from steven at gcc dot gnu dot org 2010-01-03 17:15 -------
Re. comment #11: If I configure with "--without-build-config" on
ia64-unknown-linux-gnu, with -fgcse-sm enabled, then the bootstrap completes
successfully (all languages except ada). If I configure without the extra
option, the bootstrap fails. You say that it might be "just a compare-debug
failure" -- what does that mean and what can/should I do about it?
