Running following

	int aa[int];
	
	aa[10] = 123;
	auto p = &aa[10];
	writeln(*p);

	aa[11] = 121; // add Element
	writeln(*p);

	aa[10] = 1; // change Element
	writeln(*p);

	aa.rehash; // reorganize
	writeln(*p);

	aa.remove(10);
	aa[10] = 3; // remove & add Element
	writeln(*p);	

results in

123 // correct
123 // correct
1 // correct
1 // correct because I'm lucky
1 // wrong

What Alis said is "rehash", a combination of remove/add or any 
other reorganisation, which could change memory usage and data 
locations.
By the way...why do you need a pointer to an AA-Element?
