[Bug fortran/31225] New: gfortran dislikes implicitly type subroutine arguments

[fxcoudert at gcc dot gnu dot org]

The following valid code is rejected by gfortran: (When the lines giving
explicit type to mode and dis are uncommented, gfortran compiles it fine.)

$ cat a.f90     
subroutine mysub1(a,b,mode,dis)
!  integer :: mode
!  real :: dis
  dimension a(abs(mode)),b(int(dis))
  print *, mod
  write (*,*) abs(mode), nint(dis)
end subroutine

program testprog
  call mysub1((/1.,2./),(/1.,2.,3./),-2, 3.2)
end
$ gfortran a.f90
a.f90:4.18:

  dimension a(abs(mode)),b(int(dis))
                 1
Error: 'a' argument of 'abs' intrinsic at (1) must be a numeric type
a.f90:4.31:

  dimension a(abs(mode)),b(int(dis))
                              1
Error: 'a' argument of 'int' intrinsic at (1) must be a numeric type
