LNK1120 error

I'm learning genetic algorithms and am having a linking error. The code compiles fine, but something is wrong with the linking part. I pruned out all the unneeded code. The problems somewhere in the function void init_population(ga_vector &population). I'm using Visual C++ 2008.

I've removed everything except the bare frame for SDL and am still get the linking error.

1>main.obj : error LNK2019: unresolved external symbol __imp___CrtDbgReportW referenced in function "public: __thiscall std::_Vector_const_iterator<struct ga_struct,class std::allocator<struct ga_struct> >::_Vector_const_iterator<struct ga_struct,class std::allocator<struct ga_struct> >(struct ga_struct *,class std::_Container_base_secure const *)" (??0?$_Vector_const_iterator@Uga_struct@@V?$alloca tor@Uga_struct@@@std@@@std@@QAE@PAUga_struct@@PBV_ Container_base_secure@1@@Z)

fatal error LNK1120: 1 unresolved externals

Code:

#include <SDL.h>
#include <string>
#include <vector>

#define GA_POPSIZE				2048				// ga population size
#define GA_MOVES				80					// movement points

struct ga_struct
{
	std::string str;
	unsigned int fitness;
	float matingPossibility;
};

typedef std::vector<ga_struct> ga_vector;

void init_population(ga_vector &population)
{
	int moves = GA_MOVES * 2;
	int pSize = GA_POPSIZE;

	for(int i = 0; i < pSize; i++)
	{
		ga_struct citizen;

		citizen.fitness = 0;
		citizen.matingPossibility = 0.0f;
		citizen.str.erase();

		for(int j = 0; j < moves; j++)
			citizen.str += (rand()%2) + 48;

		population.push_back(citizen);
	}
}


int main( int argc, char* args[] )
{
    //Start SDL
    SDL_Init( SDL_INIT_EVERYTHING );

	ga_vector pop_alpha;

	init_population(pop_alpha);
    
    //Quit SDL
    SDL_Quit();
    
    return 0;    
}

I've googled LNK1120 and it is sometimes a problem with the prototypes. I've tried a lot of different combinations, but haven't had any luck.

Thanks for reading over it.
