scan-build was tripped off by "result" not being used, the value of result gets overwritten by the general else in line 172 after if(y1==0||y2==0) result = 0;

Starting at line 164 of G4NeutronHPInterpolator.hh:

inline G4double G4NeutronHPInterpolator::
	LogarithmicLogarithmic(G4double x, G4double x1, G4double x2, G4double y1, G4double y2) const
	{
	G4double result;
	if(x==0) result = y1+y2/2.;
	else if(x1==0) result = y1;
	

	else if(x2==0) result = y2;
	if(y1==0||y2==0) result = 0;
	else
	{
	result = LinearLinear(std::log(x), std::log(x1), std::log(x2), std::log(y1), std::log(y2));
	result = std::exp(result);
	}
	return result;
	}

I don't know if this has any consequences when running G4
