Hm, so it may be a memory management problem. Can you try

dGv = prod<vector<double> >(dG,v);
This forces the product to be computed in a temporary before calling the copy constructor.

Can you debug what happens at this line? Maybe there is just a missing check in vector::resize() or unbounded_array::resize().

If this does not help, send me a package. However it will take a few days until I can investigate this.
