! { dg-do run }
!
! Test the fix for PR84109 in which the call to the elemental function
! 'adjustl' was being added before the scalarization loop in the assignment.
! Since the result temporary was being declared in the loop body, this
! drove the gimplifier crazy. It is sufficient to compile this testcase
! since it used to ICE. This is the intrinsic counterpart to PR87239,
! which is tested for the absence of an ICE in elemental_function_2.f90.
! In this fix, a further improvement was to keep scalar calls outside the
! scalarization loop and this is tested with 'my_adjustl'.
