Example Fortran code derived from BLAS ZGEMM routine.

  SUBROUTINE Z ( M, N, C, LDC )
* .. Scalar Arguments ..
  INTEGERM, N, LDC
* .. Array Arguments ..
  COMPLEX*16 C( LDC, * )
* .. Local Scalars ..
  INTEGERI, J
* .. Parameters ..
  COMPLEX*16 ZERO
  PARAMETER( ZERO = ( 0.0D+0, 0.0D+0 ) )
*
DO 20, J = 1, N
   DO 10, I = 1, M
  C( I, J ) = ZERO
   10  CONTINUE
   20   CONTINUE
*
  RETURN
  END

Confirmed, C testcase which shows that this is defintely a regression:
void f(double _Complex *f,int len)
{
  int i = 0;
  for(i = 0 ;i20;i++)
  {
*f = 0.0;
f++;
  }
}
