Various version of gcc, when compiling with -Og, complain:
libxl_dm.c: In function ‘libxl__write_stub_dmargs’:
libxl_dm.c:2166:16: error: ‘dmargs’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
rc = libxl__xs_write_checked(gc, t, path, dmargs);
~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It can't, but only because of how the is_linux_stubdom checks line up.
