Probably, it means that the bug is papered over. Honza promised to have a look at this, so I'm assigning this bug to him. Notice, this is not a regression, since it is caused by -fsched2-use-traces which did not exist in 3.3. -- What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |hubicka at gcc dot gnu dot |dot org |org Status|UNCONFIRMED |ASSIGNED Ever Confirmed| |1 Known to fail| |3.4.0 Known to work| |4.0.0 Last reconfirmed|0000-00-00 00:00:00 |2004-10-06 23:15:21 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15439 ^ permalink raw reply [flat|nested] 5+ messages in thread
