James Cloos 04211c3532 Prevent the -wm command line option from causing a SEGV ... The -wm (when mapped) option for the BackingStore support has been causing the server to dereference a NULL pointer. This has probably been the case since backing store has been implemented on top of Composite. It looks like (some of?) Composite didn’t expect its WIndowPtr argument to be the root window. In Composite’s compCheckRedirect() function we now avoid calling compAllocPixmap() and compFreePixmap() when the pWin pointer’s parent member is NULL, as is it the case with a server’s root window.
