patch 9.0.2140: [security]: use-after-free in win-enter
Problem: [security]: use-after-free in win-enter
Solution: validate window pointer before calling win_enter()
win_goto() may stop visual mode, if it is active. However, this may in
turn trigger the ModeChanged autocommand, which could potentially free
the wp pointer which was valid before now became stale and points to now
freed memory.
So before calling win_enter(), let's verify one more time, that the
wp pointer still points to a valid window structure.
Reported by @henices, thanks!

README_ami.txt for version 9.0 of Vim: Vi IMproved. This file explains the installation of Vim on Amiga systems. See README.txt for general information about Vim. Unpack the distributed files in the place where you want to keep them. It is wise to have a "vim" directory to keep your vimrc file and any other files you change. The distributed files go into a subdirectory. This way you can easily upgrade to a new version. For example: dh0:editors/vim contains your vimrc and modified files dh0:editors/vim/vim54 contains the Vim version 5.4 distributed files dh0:editors/vim/vim55 contains the Vim version 5.5 distributed files You would then unpack the archives like this: cd dh0:editors tar xf t:vim90bin.tar tar xf t:vim90rt.tar Set the $VIM environment variable to point to the top directory of your Vim files. For the above example: set VIM=dh0:editors/vim Vim version 5.4 will look for your vimrc file in $VIM, and for the runtime files in $VIM/vim54. See ":help $VIM" for more information. Make sure the Vim executable is in your search path. Either copy the Vim executable to a directory that is in your search path, or (preferred) modify the search path to include the directory where the Vim executable is.
