* [Bug fortran/35865] New: Spurious warning for vector-valued functions passed as arguments @ 2008-04-08 1:41 john dot young at jrc dot co dot jp 2008-04-08 1:42 ` [Bug fortran/35865] " john dot young at jrc dot co dot jp ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: john dot young at jrc dot co dot jp @ 2008-04-08 1:41 UTC (permalink / raw) To: gcc-bugs In the code below, the following warning is produced "Waring: Actual argument contains too few elements for dummy argument 'func' (1/3) at (1)" If the function result is changed to a scalar instead of a vector, no warning is produced. I do not know the standard well enough to know if this is a problem, but other compilers (G95,Intel) do not produce a warning. The function arguments do match however. I obtained this from "GCC 4.3.0 20080212 (experimental) [trunk revision 132252]" using cygwin under WinXP. !=============================================== module vec_func implicit none contains !=============================================== !=============================================== !function vector_func(func,r1) result(res) function vector_func(func) result(res) implicit none interface function func(r) result(res) implicit none real, intent(in) :: r real :: res(3) end function func end interface real :: res(3) res = func(0.) end function vector_func !============================== function test_func(r) result(res) implicit none real,intent(in) :: r real :: res(3) res = r end function test_func !========================================= end module vec_func !========================================= program a use vec_func implicit none real :: z(3) z = vector_func(test_func) print*, z end program a !========================================= -- Summary: Spurious warning for vector-valued functions passed as arguments Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: john dot young at jrc dot co dot jp GCC target triplet: i686-pc-cygwin http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35865 ^ permalink raw reply [flat|nested] 4+ messages in thread
