------- Comment #3 from pinskia at gcc dot gnu dot org 2006-11-24 02:51 ------- Most likely something is being hashed by addresses and then transversing the hashtable or an unstable sort due to using addresses as the last compare. A lot of these issues were fixed in 4.2.0 so this might be fixed already.
