The README files in the tarball, show that when an array is declared
double V[N];
or
double* V = new double[N];
computations with values stored in that array give different results!
Should floating point calculations with values stored in an array
depend on the way that array has been allocated? Both g++-3.4.2
and icc-8.1.022 exhibit similar behaviour with icc being both more
accurate and much faster on a pentium4 Laptop.
