Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: Joost.VandeVondele at mat dot ethz.ch I've noticed that for this code: SUBROUTINE S1() INTEGER, POINTER, DIMENSION(:) :: v INTERFACE SUBROUTINE foo(v) INTEGER, POINTER, DIMENSION(:) :: v END SUBROUTINE END INTERFACE CALL foo(v) END SUBROUTINE S1 gfortran initializes the pointer (to zero) even if '-fno-init-local-zero' : s1 () { struct array1_integer(kind=4) v; v.data = 0B; foo (&v); } I don't think this is mandated (other compilers don't) I'm working on a patch. ^ permalink raw reply [flat|nested] 5+ messages in thread
