I am afraid I don't understand the process. How can an ice-on-valid-code be a

duplicate of a ice-on-invalid-code? Yes, the cause for the crash might

technically be the same, but in the other case it might be covered by

undefined behaviour, here not.

   Summary: ICE on ARM for __attribute__ ((vector_size (8 *
