I will submit a patch after the tree-ssa gets merged into the mainline for this and offsetof working with this lowering disabled. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |pinskia at gcc dot gnu dot | |org BugsThisDependsOn| |14029 Status|UNCONFIRMED |ASSIGNED Ever Confirmed| |1 Keywords| |wrong-code Last reconfirmed|0000-00-00 00:00:00 |2004-05-03 14:47:10 date| | Target Milestone|--- |tree-ssa http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15262
