Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2013-03-01 02:56:39 UTC --- the array x does not have to be 16 byte aligned so it is crashing when it is doing the load. You are using the incorrect intrinsic for this load, you should be using the unaligned load one instead.
