! { dg-do run }
! Tests the fix for pr28167, in which character array constructors
! with an implied do loop would cause an ICE, when used as actual
! arguments.
!
! Based on the testscase by Harald Anlauf <anlauf@gmx.de>
!
character(4), dimension(4) :: c1, c2
integer m
m = 4
! Test the original problem
call foo ((/( 'abcd',i=1,m )/), c2)
if (any(c2(:) .ne. (/'abcd','abcd', &
'abcd','abcd'/))) call abort ()
! Now get a bit smarter
call foo ((/"abcd", "efgh", "ijkl", "mnop"/), c1) ! worked previously
call foo ((/(c1(i), i = m,1,-1)/), c2) ! was broken
if (any(c2(4:1:-1) .ne. c1)) call abort ()
! gfc_todo: Not Implemented: complex character array constructors
call foo ((/(c1(i)(i/2+1:i/2+2), i = 1,4)/), c2) ! Ha! take that..!
if (any (c2 .ne. (/"ab ","fg ","jk ","op "/))) call abort ()
! Check functions in the constructor
call foo ((/(achar(64+i)//achar(68+i)//achar(72+i)// &
achar(76+i),i=1,4 )/), c1) ! was broken
if (any (c1 .ne. (/"AEIM","BFJN","CGKO","DHLP"/))) call abort ()
contains
subroutine foo (chr1, chr2)
character(*), dimension(:) :: chr1, chr2
