iPhone table header labels not showing up in Release build but show up OK in Debug build

Question

My table header labels shows up ok with Release build or Debug build for the iPhone simulator, but the table header labels only show up with debug build on the iPhone. No table header labels show up on the iPhone for release build.

Any ideas?

Thanks, Robert

My code for the header is below

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)sectionNum
{
@try {

// create the parent view that will hold header Label
UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(HEADER_RELX_OFFSET, HEADER_RELY_OFFSET, HEADER_ROW_WIDTH, HEADER_HEIGHT)] autorelease];
UILabel* headerLabel = [[UILabel alloc] initWithFrame:CGRectZero];

headerLabel.backgroundColor = [UIColor clearColor];
headerLabel.opaque = NO;
headerLabel.numberOfLines = 0;
headerLabel.textColor = [UIColor blackColor];
headerLabel.highlightedTextColor = [UIColor whiteColor];
headerLabel.font = [UIFont boldSystemFontOfSize:HEADER_FONT_SIZE];
headerLabel.textAlignment = UITextAlignmentCenter; 
headerLabel.lineBreakMode = UILineBreakModeWordWrap;
headerLabel.frame = CGRectMake(HEADER_RELX_OFFSET, HEADER_RELY_OFFSET, HEADER_ROW_WIDTH, HEADER_HEIGHT);

if(sectionNum == 0)
  headerLabel.text = @"My Label"; 
else 
 headerLabel.text = @"";

[customView addSubview:headerLabel];  
return customView;

@catch (NSException* exception) {  
  NSLog(@"viewForHeaderInSection: %@: %@",[exception name],[exception reason]);  
}
}
