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!

# # Makefile for VIM on Win32, using MinGW cross compiler on Cygwin # # Also read INSTALLpc.txt! # # This compiles Vim as a Windows application. If you want Vim to run as a # Cygwin application use the Makefile (just like on Unix). # # The old Make_cyg.mak (maintained by Dan Sharp et al.) was merged into # Make_cyg_ming.mak. Note: USEDLL option was removed. # This file contains Cygwin specific settings. Common settings are contained # in Make_cyg_ming.mak. # # Last updated by Ken Takata. # Last Change: 2014 Oct 21 # uncomment 'PERL' if you want a perl-enabled version #PERL=/cygdrive/c/perl # uncomment 'LUA' if you want a Lua-enabled version #LUA=/cygdrive/c/lua # uncomment 'MZSCHEME' if you want a MzScheme-enabled version #MZSCHEME=/cygdrive/d/plt # uncomment 'PYTHON' if you want a python-enabled version #PYTHON=/cygdrive/c/python20 # uncomment 'PYTHON3' if you want a python3-enabled version #PYTHON3=/cygdrive/c/python31 # uncomment 'TCL' if you want a Tcl-enabled version #TCL=/cygdrive/c/tcl # uncomment 'RUBY' if you want a Ruby-enabled version #RUBY=/cygdribe/c/ruby # Use MinGW-w64 cross compiler. # There are two MinGW-w64 packages in Cygwin: # 32-bit: mingw64-i686-gcc-g++ # 64-bit: mingw64-x86_64-gcc-g++ # You may also need to set 'ARCH' in Make_cyg_ming.mak.
