>Description:
This code causes g++ to feel segmentation fault. I've replaced initializer for base class Smoother(size) with Smoother_Lookup(size):

template<typename Function>
class Smoother_Lookup : public Smoother {
public:
	Smoother_Lookup(int size) : Smoother_Lookup(size), lookup(size) {
		std::generate_n(lookup.begin(), size, Function(size));
	}
	int smooth(int r) { return lookup[r]; }
protected:
	std::vector<int> lookup;
};
>How-To-Repeat:
Try to compile test.cpp:

make test.o
>Fix:

#include <vector>

class Smoother {
public:
	Smoother(int size) : _size(size) { }
	virtual ~Smoother() = 0;
	virtual int smooth(int r) = 0;
protected:
	int _size;
};

template<typename Function>
class Smoother_Lookup : public Smoother {
public:
	Smoother_Lookup(int size) : Smoother_Lookup(size), lookup(size) {
		std::generate_n(lookup.begin(), size, Function(size));
	}
	int smooth(int r) { return lookup[r]; }
protected:
	std::vector<int> lookup;
};

struct Test {
	int operator()() { return 0; }
};

int
f() {
	Smoother_Lookup<Test> sl(1);
}
