        * regrename.c (replace_oldest_value_reg): Use validate_change with
        IN_GROUP set to 1 instead of doing direct modifications.
        (copyprop_hardreg_forward_1): Likewise.  If any replace_oldest_*
        replacements have been performed on an instruction, use
        apply_change_group ().

        * g++.dg/opt/pr25005.C: New test.
