From: "mrestelli at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/63867] New: LEN is lost for a CHARACTER variable inside SELECT TYPE Date: Fri, 14 Nov 2014 11:42:00 -0000 [thread overview] Message-ID: <bug-63867-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63867 Bug ID: 63867 Summary: LEN is lost for a CHARACTER variable inside SELECT TYPE Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: mrestelli at gmail dot com Consider the following code: program p implicit none character(len=5) :: str str = 'abcde' call checklen1(str) call checklen2(str) contains subroutine checklen1(s) character(len=*), intent(in) :: s call checklen2(s) end subroutine checklen1 subroutine checklen2(s) class(*), intent(in) :: s select type(s) type is(character(len=*)) write(*,*) "Len is ",len(s) write(*,*) "s is ",s end select end subroutine checklen2 end program p When compiled with gfortran it prints $ ./test Len is 0 s is Len is 5 s is abcde while the expected output is twice the same, i.e. $ ./test Len is 5 s is abcde Len is 5 s is abcde I.e., inside the SELECT TYPE the lenght of the string is lost, but only when the actual argument is itself a dummy argument with LEN=* . $ gfortran --version GNU Fortran (GCC) 5.0.0 20141114 (experimental) Marco
