Modify const reference data

Hello,

I've been strugling with a solution before bothering you guys 
here (again). I have my own complex code but i made a VERY simple 
test case to reproduce my problem, here's the code:

private import std.stdio;

class A
{
	private const ubyte* data;
	private ubyte[] abc;
	
	this()
	{
		abc = [1,2,3,4];
		data = cast(const ubyte*)abc.ptr;
	}
	
	public void print()
	{
		for(size_t i = 0; i < 4; i++)
		{
			writefln("%d", data[i]);
		}
	}
}

class B
{
	private const ubyte* data;
	private ubyte[] abc;
	
	this()
	{
		data = cast(const ubyte*)abc.ptr;
	}
	
	public void foo()
	{
		abc = [1,2,3,4];
	}
	
	public void print()
	{
		for(size_t i = 0; i < 4; i++)
		{
			writefln("%d", data[i]);
		}
	}
}

void main()
{
	A a = new A();
	a.print(); // OK.
	
	B b = new B();
	b.print(); // Crash.
}

The thing is that i can not use the data that const variable 
"data" in class B is referencing because in my original code i 
get "Invalid Memory Operation", in the test case i get "access 
violation" but it doesn't matter the name of the exception, the 
only thing that matters is that the exception raises for the same 
reason. I understand that i should not modify the const data 
outside a constructor but by stricts reason i can't avoid that.

Do you guys have any other aproach to get away with this? (modify 
a const reference data and then manipulate that data). THANK YOU 
very much in advance. D2 learner by the way.
