[Bug tree-optimization/41287] [4.4 Regression] -O1 optimisation of for loops in some cases omits essential functionality resulting in failed applications

[rguenth at gcc dot gnu dot org]

------- Comment #3 from rguenth at gcc dot gnu dot org  2009-09-07 09:45 -------
Works for me with g++-4.4 (Debian 4.4.1-3) 4.4.1.  But I can reproduce it with
the 4.4.1 release on both x86_64 and x86_64 with -m32.
4.4.0 seems to work, so does trunk and 4.4.2.

Thus, fixed.
