I also see it on powerpc-apple-darwin9 at revision 135683. The following
reduced case:

program test_count
    integer, dimension(2,3) :: a, b
    a = reshape( (/ 1, 3, 5, 2, 4, 6 /), (/ 2, 3 /))
    b = reshape( (/ 0, 3, 5, 7, 4, 8 /), (/ 2, 3 /))
    print '(3l6)', a.ne.b
!    print *, a(1,:).ne.b(1,:)
    print *, a(2,:).ne.b(2,:)
    print *, count(a.ne.b)
end program test_count

gives:

count_db.f90:1: internal compiler error: vector VEC(lambda_vector,base) index
domain error, in gather_interchange_stats at tree-loop-linear.c:150

If I uncomment the commented line I get:

count_db.f90:1: internal compiler error: in calculate_allocation, at vec.c:51
