 NSMutableArray *foo = [NSMutableArray arrayWithCapacity:12];
 NSLog(@" foo is 0x%x", foo);  // worked in XCode 4.0 to return the hex address of this variable     

Now it gives compiler warning:

Conversion specifies type 'unsigned int' but the argument has type 'NSMutableArray'

How do I get output like "foo is 0x53a6d0" for example?
