Luigi,

It was Luca who had the problems with MT. I had constructor problems.

Well, if a class doesn't implement a default constructor, your own code 
cannot call it :)

VC6 used to let you get away with illegal C++. VC7 and 8 don't.
Having said this, I wouldn't exclude that VC8 (being a beta) has issues.

However, I still don't have a clear picture of the problem. Is it the 
Mersenne twister (which _has_ a default constructor) that causes your code 
to fail? Or is some other class? What exactly is the offending line?

Later,
