Okay, I know I must be doing something incredibly stupid here. Here's the sample code (which, when executed within a viewDidLoad block silently crashes... no error output to debug console).

NSMutableArray *bs = [NSMutableArray arrayWithCapacity:10];
[bs addObject:[NSNumber numberWithInteger: 2]];
NSLog(@"%@", [bs count]);
[bs release];

What am I missing?

Oh... and in case anyone is wondering, this code is just me trying to figure out why I can't get the count of an NSMutableArray that actually matters somewhere else in the program.
