I found exactly the same problem with the current stable version of ZBar 0.10, and fixed it by subclassing ZBarReaderViewController and overriding the loadView method. I can now run the scanner over and over without memory going crazy.

Here's the full code:

... header

#import 
#import "ZBarReaderViewController.h"

@interface CVZBarReaderViewController : ZBarReaderViewController
@end

.. and the implementation

#import "CVZBarReaderViewController.h"

@implementation CVZBarReaderViewController 
- (void) loadView
{
    self.view = [[[UIView alloc] initWithFrame: CGRectMake(0, 0, 320, 480)] autorelease];
}
@end

Remember to mark the .m file as being non-arc. Go to Project Settings / Target / Build Phases / Compile Sources and mark CVZBarReaderViewController.m with -fno-objc-arc.
