+       * pei-x86_64.c (pex64_get_unwind_info): Change to a boolean
+       function.  Add an end address parameter.  Check access of the data
+       pointer to make sure that they do not extend beyond the end
+       address.  Return FALSE if any check fails.  Add the end address
+       pointer to the ui structure.
+       (pex64_xdata_print_uwd_codes): Check accesses of the raw unwind
+       codes to make sure that they do not extend beyond the end address
+       pointer.  Print an error message and return immediately if any
+       check fails.
