> This doesn't compile with g++ 2.95.2:

> This is actually a problem with the valarray constructor that takes a gslice as an argument,
which is called by the valarray::operator[] ( gslice );. in fact, the following code would
cause the core dump:
> ------
> #include <valarray>
> int main()
> {  
>    std::valarray<double> dval;
>    dval[std::gslice()];
> }
> -----
