I have marked it as 'confirmed'. There are no problems with kernel 3.7.0 on my machine.
I did boot kernel-3.5.0-18-generic to test again and the above bug did happen. I got 'kernel BUG at /build/buildd/linux-3.5.0/mm/mmap.c:2312!' with kernel 3.5.0-18-generic within a few minutes. Thanks for all your help. I am glad it is fixed upstream. I will continue using kernel 3.7.0 as it is much more reliable than 3.5.0 on my machine anyway.
