[Bug fortran/25513] New: ICE tree check using complex numbers and the "-fno-automatic" compiler option

[harald dot vogt at desy dot de]

The following little piece of code produces an ICE if compiled with the
"-fno-automatic" compiler option:

      subroutine test
      implicit none
      complex z
      integer i,j
      do i=1,2
        do j=1,2
          z=cmplx(.5,0.)*cmplx(1.,0.)
        enddo
      enddo
      end

The compiler output is:

internal compiler error: tree check: expected ssa_name, have var_decl in
gather_mem_refs_stmt, at tree-ssa-loop-im.c:1275
Please submit a full bug report
