--- Comment #8 from Paul Thomas <pault at gcc dot gnu.org> --- I had a devil of a job fixing the second testcase, from "Blockbuster", in the clf thread above: program testdefchar implicit none character(:), allocatable :: test(:) allocate(character(3) :: test(2)) test(1) = 'abc' test(2) = 'def' write(*,*) test(1), test(2) test = ['aa','bb','cc'] write(*,*) test(1), test(2), test(3) end program testdefchar The fix is now regtesting.
