It seems r174123 (= 59813b406b20d7b) not only fixed PR rtl-optimization/48971,
but also this issue:

    2011-05-13  Vladimir Makarov  <vmaka...@redhat.com>

        PR rtl-optimization/48971
        * ira.c (setup_pressure_classes): Don't check register move cost
        for classes with one registers.  Don't add pressure class if there
        is a pressure class with the same available hard registers.
        Check contains_reg_of_mode.  Fix a typo in collecting
        temp_hard_regset.  Ignore hard registers not belonging to a class.


Since this patch, this problem is gone.

Thanks!
