Comment (by nicol):
I tried windows 7, 8.1, 10, and WLS on ubuntu. Windows 7(64bit),
8.1(32bit) are crash, but Windows 10(64bit), and WLS on ubuntu dose not
crash.
Using this gdb 64bit. http://www.equation.com/servlet/equation.cmd?fa=gdb
ffmpeg.exe -f lavfi -i testsrc2=s=640x360 -vf
crop=320:180:16:0,zscale=160:-2 -vframes 1 -f null -
