Internal compiler error with ifx

[Juergen_R_R]

Using ifx --version
ifx (IFX) 2023.1.0 20230320

the following code leads to an ICE upon compilation,

module m
  implicit none
  private
  type :: parameter_t
     private
     class(data_t), pointer :: data => null ()
  end type parameter_t

  type, abstract :: data_t
     private
   contains
     procedure :: get_real_ptr => data_get_real_ptr
  end type data_t

  type, extends (data_t) :: real_t
     private
     real :: value
  end type real_t

  type, extends (data_t) :: complex_t
     private
     complex :: value
  end type complex_t
  
  type :: t1_t
     private
     type(parameter_t), dimension(:), allocatable :: par
     type(real_t), dimension(:), pointer :: par_real => null ()
     type(complex_t), dimension(:), pointer :: par_complex => null ()
   contains
     procedure :: set => t1_set
     procedure :: get_par_real_ptr => t1_get_par_real_ptr_index
  end type t1_t

  interface
    module function data_get_real_ptr (par) result (ptr)
      class(data_t), intent(in), target :: par
      real, pointer :: ptr
    end function data_get_real_ptr
    module function t1_get_par_real_ptr_index (t1, i) result (ptr)
      class(t1_t), intent(inout) :: t1
      integer, intent(in) :: i
      class(data_t), pointer :: ptr
    end function t1_get_par_real_ptr_index
  end interface  
contains

  subroutine t1_set (t1, i, value)
    class(t1_t), intent(inout), target :: t1
    integer, intent(in) :: i
    real, intent(in) :: value
    class(data_t), pointer :: par_data
    real, pointer :: value_ptr
    par_data => t1%get_par_real_ptr (i)
    !!! triggers the ICE
    value_ptr => par_data%get_real_ptr ()
  end subroutine t1_set

end module m

Thank you for reporting this. I just tried your reproducer with the compiler that will be available in mid-2023. The ICE is gone!

I'll let you know when it's available.

I just successfully compiled the code that previously ICEd with the ifx version that will be available in a few weeks. The compiler is part of oneAPI HPC Toolkit 2023.2.
