Accessing this variable directly is a recipe for disaster, because binaries and libraries can have different versions in them due to how libshadow_la linking is performed. Make sure that at least NULL check is always performed by calling the proper getter function. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
