ICE with IFX using procedure pointers

Hi,

The attached file gives an ICE with ifx, version: (IFORT) 2023.0.0 20221201. The output is at the end of this message.

Note, that it is a very much reduced code starting from a large code and maybe it can be reduced even further, but at least it gives the same error message as the large code.

It compiles fine with ifort, gfortran and nagfor.

The output is:

[tfemuser@080a0116f9cd ifx-ice]$ ifx -c ifx-ice.f90

Below is a short reproducer, which is by the look of it, caused by the same bug in ifx, causing an ICE.

 

program proc_pointer

type :: t
   procedure(answer), nopass, pointer :: p
end type t

type(t) :: x

x%p => answer
call foo(x%p)

contains

   function answer() result(x)
      integer :: x
      x = 42
   end function answer

   subroutine foo(a)
      procedure(answer) :: a
      print *,a()
   end subroutine foo

end program proc_pointer

The bug seems to be fixed in 2023 update 1. My finite element code of near 100000 loc passes all my tests with ifx now.

Thanks for the fix.

I added the new reproducer to the bug report. Sometimes these bugs are tricky and may not have the same cause. We will see!
