patch 9.0.2129: [security]: use-after-free in call_dfunc()
Problem: [security]: use-after-free in call_dfunc()
Solution: Refresh dfunc pointer
closes: #13571
This Commit fixes a SEGV caused by a use-after-free bug in call_dfunc().
When calling check_ufunc_arg_types() from the call_dfunc() it may cause
def functions to be re-compiled and if there are too many def functions,
the def_functions array will be re-allocated. Which means, that the
dfunc pointer in call_dfunc() now starts pointing to freed memory.
So we need to reset the dfunc pointer after calling
check_ufunc_arg_types().
Let's also add a test, to ensure we do not regress.

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.
