--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
The benchmark somehow iterates and we differ in in bwaves2.out, which is: "The
residual for convergence after each time step".
Following configuration tweak fixes the issue:
diff --git a/benchspec/CPU2006/410.bwaves/Spec/object.pm

I tend to close this as invalid..
