Yes, as you mentioned, there are only two difference. When I meet the
bug, I have no idea to deal with it. So I try several method and times
to fix it. After I changed the code up to the patch as I send to you, it
works fine. And till now I am not very such whether this bug has been
fixed. So I this patch just a try and I cannot explain it exactly even
today.
