Title:
  gdb crashes upon `run` on some arm64 machines

Status in gdb package in Ubuntu:
  New

Bug description:
  gdb 13.1 shipped in lunar, is affected by a bug where it crashes upon
  `run` on some arm64 machines (confirmed on Apple M-series, both under
  hypervisor and bare metal, everything else with PAC should also be
  affected).

  It was fixed upstream in gdb 13.2: https://inbox.sourceware.org/gdb-
  patches/20230316103904.1947447-1-luis.machado at arm.com/.

  Debian bookworm's gdb_13.1-3 also includes the same patch as
  `aarch64-pauth-registers.patch`.
