Example - NSNumber when used with __weak causes segmentation fault

Hi,

When a new NSNumber is created and is assigned to a __strong pointer variable
and later when it is assigned to __weak pointer variable it causes a
segmentation fault.

Attached below is a sample program.

Refer -
http://stackoverflow.com/questions/8125530/objective-c-arc-nsnumber-segmentation-fault

Pls look into this.

Thanks,
Muthu
