Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Without gimple front-end format we don't output if the type alignment is different. but with -gimple we do get (this is without the h field): _26 = __MEM <unsigned long, 16> ((voidD_54 *)q_2(D)); With the h field the alignment of S struct will be 64 so this is invalid.
