+       * z80-dis.c (suffix): Don't use a local struct buffer copy.
+       Peek at next byte to prevent recursion on repeated prefix bytes.
+       Ensure uninitialised "mybuf" is not accessed.
+       (print_insn_z80): Don't zero n_fetch and n_used here,..
+       (print_insn_z80_buf): ..do it here instead.
