--- Comment #13 from Richard Henderson <rth at gcc dot gnu.org> ---
FWIW,

https://gitlab.com/rth7680/qemu/-/commits/tgt-arm-gdb

adds org.gnu.gdb.aarch64.pauth support to qemu.

Run with gdb master, with any linux-user guest binary,
leads to a gdb internal abort.

(gdb) target remote :1234

../../git-src/gdb/aarch64-tdep.c:2704: internal-error:
aarch64_pseudo_register_type: bad register number 192
