The code is clearly invalid Fortran.
module m
contains
subroutine s(inp)
character(*), intent(in) :: inp
character(:), allocatable :: a
a = a ! This used to ICE.
!
! The above is an invalid reference of an unallocated allocatable on
! the RHS.
!
a = inp
a = a ! This used to ICE too
if ((len (a) .ne. 5) .or. (a .ne. "hello")) STOP 1
a = a(2:3) ! Make sure that temporary creation is not broken.
if ((len (a) .ne. 2) .or. (a .ne. "el")) STOP 2
deallocate (a)
a = a ! This would ICE too.
!
! The above is an invalid reference of an unallocated allocatable on
! the RHS.
!
end subroutine s
end module m
use m
call s("hello")
end
You either need to remove the above two lines to get a valid program
or remove the testcase as it's testing processor dependent behavior.
