Have you seem my message on IRC about changing the feature name in the
XML? I think the issue is that we're putting the .xml in a "namespace"
where GDB expects to only find stuff which it has code to
support. Changing from "org.gnu.gdb.aarch64.pauth" to
"org.qemu.aarch64.pauth" made it stop crashing and I can read the
registers just fine.
