Still fails on my machine, on rev150694.

~/gcc/svn/trunk/usr/bin/gfortran -ffast-math -funroll-loops -msse3 -O3
induct.f90 -o induct
time ./induct
real    0m16.596s
user    0m16.393s
sys     0m0.076s

~/gcc/svn/trunk/usr/bin/gfortran -fgraphite-identity -ffast-math -funroll-loops
-msse3 -O3 induct.f90 -o induct
time ./induct
real    0m25.740s
user    0m25.634s
