Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|c |middle-end Summary|[4.8 regression] Array |Array bounds violation is |bounds violation is very |very end-user unfriendly |end-user unfriendly | --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2013-03-10 20:31:49 UTC --- >From the changes page: GCC now uses a more aggressive analysis to derive an upper bound for the number of iterations of loops using constraints imposed by language standards. This may cause non-conforming programs to no longer work as expected, such as SPEC CPU 2006 464.h264ref and 416.gamess. A new option, -fno-aggressive-loop-optimizations, was added to disable this aggressive analysis. ------- CUT ---------- There is another bug opened about adding a warning already but I don't remember the number.
