Releasing modal view controller properly

I'm not using ARC so I need to take care of releasing objects manually.
I'm creating and presenting a modal UIViewController like this:
MyViewController *vc = [[MyViewController alloc] init];
vc.modalPresentationStyle = UIModalPresentationFormSheet;
vc.preferredContentSize = CGRectMake(320, 320);
[self presentViewController:vc animated:YES completion:nil]
[vc release];
When touching the modal view's close button my code does the following:
[[self presentingViewController] dismissViewControllerAnimated:YES completion:nil];
Unfortunately, the app crashes right after the modal view has completed
its transition animation.
When I disable the line "[vc release]", I don't get any crashes and it
works fine. Can anybody explain why? I was expecting that presentViewController()
retained the view controller so that it is safe for me to release it
right after making the call to presentViewController() because I don't
need it any longer but apparently, there's something wrong in my code
but I don't see it...
