And the easiest main.cpp

typedef complex<double> dcx;

typedef vector<vector<vector<double> > > dArray3D;
typedef vector<vector<double> > dArray2D;
typedef vector<double> dArray1D;

typedef vector<vector<vector<dcx> > > dcxArray3D;
typedef vector<vector<dcx> > dcxArray2D;
typedef vector<dcx> dcxArray1D;

int main(int __argc,char *__argv[]){
	C_Integrator_Cauchy<dcxArray1D,dcxArray2D,dcx> * integ_cauchy=C_Integrator_Cauchy<dcxArray1D,dcxArray2D,dcx>::createIntegrator(2000, 0.0, 6.2831, 1, qcauchyleg_lin_ID);
	
	cout << "Start allocate something" << endl;
	dcxArray2D temp;
	temp.resize(1,dcxArray1D());
	for (int i = 0; i < 8000; i++){
		temp[0].push_back(1.0);
		cout << i << endl;
	}
	cin.get();

 return 0;
}


The issue is - after creation of the Integrator_Cauchy in main.cpp, it is impossible to allocate big vector (say i > 4000). It throws:
free() invalid next size (normal) 
although i have more than enough memory space in RAM, and the Integrator_Cauchy itself doesn't take a lot of memory.

I`m compiling on Ubuntu 12.10; g++ 4.7.2;

Any ideas?

static C_Integrator_Cauchy * createIntegrator(/**/) ┬┐why? you are leaking memory, by the way.
