I'm observing the same behaviour with 10-current running as guest in VirtualBox.

 Program received signal SIGSEGV, Segmentation fault.
 0x0000000000454bec in dixLookupPrivate (privates=0x290, key=0x804e2be38) at privates.c:79

The segmentation fault in dixLookupPrivate() seems like a subsequent fault of
  xf86Init.c:1043 scr_index = AddScreen(xf86Screens[i]->ScreenInit, argc, argv);
indicating failure to add the screen.

Building xorg-server with gcc
   make USE_GCC=any
or with clang and -O0
   mage CFLAGS=-O0
gives me an X server that appears to work (displays root weave, xterm,
and twm).
