class variable accessible at end of one function, and crashes on access at beginning of next
(programming in iPhone objective-C)

I have a class level NSString* that I create, add property(nonatomic,retain) and synthesize code for and I can modify the string endlessly with stringByAppendingString functions and display the string using NSLog just fine. All of this is done in a subclass, overridden viewDidLoad function. When I try to access the same variable from the cellForRowAtIndexPath fuction when determining what to display in the cell of a tableView, the program crashes. Anyone have any clues?

Related Code:

    @interface InfoViewController : UITableViewController {
    	NSString *shipAddr;
    }
    @property (nonatomic,retain) NSString *shipAddr;

    @synthesize shipAddr;

VIEWDIDLOAD:

    shipAddr = [[[NSString alloc] initWithString:@""] retain];


**CRASHES HERE:

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    	NSLog(shipAddr);
