  Exception 0xc0000005 at this address:
  Fbackward_prefix_chars at syntax.c:3036

  Backtrace:
  w32_backtrace at w32fns.c:8490
  emacs_abort at w32fns.c:8522
  terminate_due_to_signal at emacs.c:383
  handle_fatal_signal at sysdep.c:1654
  deliver_thread_signal at sysdep.c:1628
  deliver_fatal_thread_signal at sysdep.c:1666

I have no idea why DEC_BOTH at line 3036 of syntax.c should segfault.
