No, it is a bug in the code. std::min is declared as
template <class T> const T& min(const T& a, const T& b);
so the two parameters need to be of the same type. The call looks like
Where nStars is unsigned int and solarSystems-size() is size_t. On 32
bit systems, size_t happens to be identical to unsigned int, so the
bug goes unnoticed. The fix is to declare nStars as size_t, or to
cast one of the parameters.
