It can. If you e.g. comment out the line

  attr.window_type = GDK_WINDOW_TOPLEVEL;

then the program will abort with

$ ./cairo_test

(cairo_test:21183): Gdk-WARNING **: 
/build/buildd-gtk+3.0_3.0.8-1-i386-1AHGdN/gtk+3.0-3.0.8/./gdk/gdkwindow.c:1342cannot 
make windows of type 8
Cannot make toplevel window!

Please note that the "Cannot make toplevel window!\n" string is only 
printer if (!win).
