--- Comment #3 from ktkachov at gcc dot gnu.org ---
Marking as P1. We hit this with a Fortran reproducer:
      SUBROUTINE REPRODUCER( M, A, LDA )
      IMPLICIT NONE
      INTEGER            LDA, M, I
      COMPLEX            A( LDA, * )
      DO I = 2, M
        A( I, 1 ) = A( I, 1 ) / A( 1, 1 )
      END DO
      RETURN
      END

on aarch64 with -march=armv8-a+sve -O3
The ICE triggeres on 12.3 but compiles fine wiht 12.2
