New patch change "record_gdb_operation_disable_set" to:
struct cleanup *
record_gdb_operation_disable_set (void)
{
  struct cleanup *old_cleanups = NULL;

  if (!record_gdb_operation_disable)
    {
      old_cleanups =
        make_cleanup_restore_integer (&record_gdb_operation_disable);
      record_gdb_operation_disable = 1;
    }

  return old_cleanups;
}
Because the old one work not very well if call
record_gdb_operation_disable_set a lot of time before clean it.

Thanks,
Hui
