GA1DArrayAlleleGenome & GASharing

[G.Spagnuolo]

Hi all!
I am working with galib under VC++6.0 and I need to use the genome class 
GA1DArrayAlleleGenome (or GARealGenome with alleles) together with the 
GASharing scaling function.
In the following I report a test example to clarify my problem.
I have the first gene whose value is in the set [1..10] and the second one 
whose value is in the range [2..8], both integers.
The compiler gives no errors during compiling, linking and so on, but I 
have a runtime error when the line

ga.scaling(scale);

is executed.
In particular, the error occurs when

   sclscm = s.clone();

is executed.
Of course, I have the same error if I use the GARealGenome with alleles.

Any hint?

Thanks in advance.
