I have an app, which made it to the App Store just a few days ago. But I
received a few crash reports from some users.

*The information is as following:*

Exception Type:  EXC_BAD_INSTRUCTION (SIGILL)
Exception Codes: 0x0000000000000001, 0x0000000000000000

Application Specific Information:
objc[3449]: garbage collection is OFF
objc[3449]: cannot form weak reference to instance (0x10e761920) of class
LSMainWindowController

*In the LSMainWindowController, I have the following declaration:*
@property(unsafe_unretained, nonatomic) IBOutlet LSTextView *textView;
#if __has_feature(objc_arc_weak)
@property(weak, nonatomic) LSAppDelegate *appDelegate;
#else
@property(unsafe_unretained, nonatomic) LSAppDelegate *appDelegate;
#endif

*In the applicationDidFinishLaunching method in AppDelegate:*
if (!_mainWindowController) {
    _mainWindowController = [[LSMainWindowController alloc]
initWithWindowNibName:@"LSMainWindow"];
}
[_mainWindowController showWindow:self];


Any thoughts? Really need to fix this as soon as possible.
