Sleep is for the weak

For lack of anything better to post, I'll share a stupid mistake I've made with you all. I created a function object for use with the std::sort() algorithm that depended on a external object, so I decided to store a reference. It basically looked like:

class Sorter {
Sorter(const Object ref) : ref_(ref) {}
// other stuff
const Object & ref_;

See what the problem is? That's right, I ended up storing a reference to the parameter that was passed on the stack.
