Thread 1: Program received signal: “EXC_BAD_ACCESS”

[redpotato]

I just have a simple code to practice Object C..
I am not sure why I can this "WARNING"?
My code is below

#import <Foundation/Foundation.h>


@interface MyClass : NSObject {
@private
NSDate *mdate;
}

@property (retain) NSDate *mdate;

@end
==================================

#import "MyClass.h"


@implementation MyClass

@synthesize mdate;

- (id)init
{
self = [super init];
if (self) {
// Initialization code here.
mdate = [[NSDate date] autorelease];
}

return self;
}

- (void)dealloc
{
[super dealloc];
}

@end
=============================================


#import <Foundation/Foundation.h>
#import "MyClass.h"

int main (int argc, const char * argv[])
{

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

MyClass *mclass = [[MyClass alloc]init];
NSDate *myBirthday;
NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init];
[dateFormat setDateFormat"yyyy/MM/dd"];
myBirthday=[dateFormat dateFromString"1990/09/02"];

[mclass setMdate:myBirthday];
NSLog(@"My Birthday is %@",[mclass mdate]);
// insert code here...
NSLog(@"Hello, World!");

[mclass release];
//[dateFormat release];

[pool drain];
return 0;
}

and in [pool drain] -> i got the message after I ran.

I am really newbie on Object C. Could someone please explain what I missed?
I think this cause my memory management(?)

You are on the C language forum.
It's interesting to know: the C is not the same language as Objective C.
