[Bug c++/18216] New: Different results when an array is statically/dynamically allocated

["dkouroun at mailbox dot gr" <gcc-bugzilla at gcc dot gnu dot org>]

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.
