Various version of gcc, when compiling with -Og, complain:
xenstored_control.c: In function ‘lu_read_state’:
xenstored_control.c:540:11: error: ‘state.size’ is used uninitialized in this
function [-Werror=uninitialized]
if (state.size == 0)
~~~~~^~~~~
xenstored_control.c:543:6: error: ‘state.buf’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
pre = state.buf;
~~~~^~~~~~~~~~~
xenstored_control.c:550:23: error: ‘state.buf’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
(void *)head - state.buf < state.size;
~~~~~^~~~
xenstored_control.c:550:35: error: ‘state.size’ may be used uninitialized in

for the stubdom build. This is because lu_get_dump_state() is a no-op stub in
MiniOS, and state really is operated on uninitialised.
