Very strange dealloc behavior - did not receive a call

Question

I tested all the dealloc viewControllers methods. And they are all called properly when calling popViewControllerAnimated.

But only one controller dealloc method is not called. I can not understand the problem.

When I clicked on this controller, I wrote the following code correctly:

AController *contr = [AController alloc]initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:contr animated:YES];
[contr release];

and when I return from the controller, I wrote:

[self.navigationController popViewControllerAnimated:YES];

This is a really strange behavior because this code is written on many controllers and works fine.
