Here a small rewrite program bug implicit none real, target, allocatable :: a(:,:) allocate(a(10,10)) a = 1.0 print*, f(a) contains function f(b) result(x) real, target, intent(in):: b(:,:) real, pointer :: c(:,:) real :: x(size(c(1,:))) c => b(1:2,:) x = c(2,:) end function f end program bug The line 'real :: x(size(c(1,:))' is referencing an unassociated pointer. If I add the 'integer :: n = size(c(1,:)) I get % gfc6 -c bug.f90 bug.f90:15:29: integer :: n = size(c(1,:)) 1 Error: Deferred array 'c' at (1) is not permitted in an initialization expression A similar error should probably occur here. ^ permalink raw reply [flat|nested] 4+ messages in thread
