------- Comment #3 from pinskia at gcc dot gnu dot org  2010-07-05 01:26 -------
Does not warn with:
GNU C++ (GCC) version 4.6.0 20100627 (experimental) [trunk revision 161476]
(x86_64-unknown-linux-gnu)
        compiled by GNU C version 4.6.0 20100627 (experimental) [trunk revision
161476], GMP version 4.3.2, MPFR version 2.4.2, MPC version 0.8.1


Though we could have the same issue:
<bb 4>:
  # i_29 = PHI <1(3), 0(6)>
  # point$x$_18 = PHI <point$x$_8(3), point$x$_17(6)>

<bb 5>:
  # i_1 = PHI <i_29(4), 0(2)>
  # point$x$_17 = PHI <point$x$_18(4), point$x$_3(D)(2)>

Why aren't those two BB's combined?
