This bug is fixed by following chage in GCC 3.0.
gcc/gcc/ChangeLog.3:
2000-04-24 Hiroyuki Machida <machida@sm.sony.co.jp>
* combine.c (try_combine): Update reg_nonzero_bits of
newi2pat before newpat.
Please refer mail archives at gcc.gnu.org for details.
You can easily apply this fix to gcc-2.95.x.
