--- Comment #11 from Janne Blomqvist <jb at gcc dot gnu.org> ---
Yes, makes sense. And the same happens if one uses an external function with a
hand-rolled interface declaration:
function chararray2string(chararray) result(text)
character(len=1), dimension(:) :: chararray ! input
character(len=int(size(chararray, 1), kind=8)) :: text ! output
print *, ">", chararray, "<"
do i = 1,size(chararray,1)
text(i:i) = chararray (i)
end do
print *, ">", text, "<"
end function chararray2string
program TestStringTools
interface
function chararray2string(chararray) result(text)
character(len=1), dimension(:) :: chararray ! input
character(len=int(size(chararray, 1), kind=8)) :: text ! output
end function chararray2string
end interface
character(len=52) :: txt
character(len=1), dimension(52) :: chararr = &
(/(char(i+64),char(i+96), i = 1,26)/)
print *, ">", chararr, "<"
txt = chararray2string(chararr)
if (txt .ne. "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz") &
STOP 1
end program TestStringTools
