This fails for me on AMD64 even with -fno-web. 
 
$ cat elemental-reduced.f90 
! Program to test elemental functions. 
program test_elemental 
   implicit none 
   integer, parameter :: N = 8 
   integer(kind = 4), dimension (N) :: a 
   integer(kind = 4), dimension (N) :: b 
   integer i 
 
   a = 2 
   b = e_fn (2, 0) 
 
   a = e_fn (a(N:1:-1), b) 
 
   do i = 1,N 
      if (a(i) /= 0) call abort 
   end do 
 
contains 
 
   elemental integer function e_fn (p, q) 
      implicit none 
      integer, intent(in) :: p, q 
      e_fn = p - q 
   end function 
 
end program 
$ gfortran -static elemental-reduced.f90 -O3 -funroll-loops 
$ ./a.out 
Aborted 
$ gfortran -static elemental-reduced.f90 -O3 -funroll-loops -fno-web 
$ ./a.out
