Hi Yegappan

It does not crash for me (Vim-7.3.884 GTK2, on Linux x86_64).

But I think it's best to give a completely automated way of reproducing
the bug using -u NONE if possible.

I try to reproduce your steps in a automated way using this command:

$ vim -u NONE \
   -c 'call feedkeys("i\<C-R>=repeat('"'a'"', 262040)\<CR>\<Esc>:sleep
5\<CR>Vy:sleep 7\<CR>llllhhhlllll")'

Does it crash for you with this command?  Or can you add what's
missing to that command to trigger the crash?

Regards
Dominique
