Failing to Release after Multiple Nib loads

Question

I am using a Nib as a template for several buttons. It seemed to work fine, they each have their own independent state. However when I went to release the buttons I would crash in the dealloc. Here is the code...

mSoundBtns = new cSoundButton*[mNumSounds];
for(unsigned int i = 0 ; i < mNumSounds; ++i) {
    mSoundBtns[i] = nil;
}

for(unsigned int s = 0; s < mNumSounds; ++s) {

    [[NSBundle mainBundle] loadNibNamed:@"InstanceSoundButton" owner:self options:nil];
    //Auto Loads via Outlet into 'soundNib'

    mSoundBtns[s] = soundNib;
    soundNib = nil;

    uint32 count = mSoundBtns[s].retainCount;
    NSLog(@"Last Count: %d", count);
}


for(unsigned int j = 0; j < mNumSounds; ++j) {
    [mSoundBtns[j] release];  //**** Crash here on 7th (of 8) release
    mSoundBtns[j] = nil;
}

Header:

@interface cLocationContext {
   ...

   cSoundButton** mSoundBtns;
   IBOutlet cSoundButton* soundNib;

}

@property (nonatomic, assign) IBOutlet cSoundButton* soundNib;

@end

The Nib is very simple, it just include a parent view and a child view of a custom view type.

cSoundButton simply keeps track of a name and a boolean state Mute or Not. Here is the dealloc

- (void)dealloc {

    delete[] mSoundTag;

    // Call the inherited implementation
    [super dealloc];  //****Crashes in here
}

The crash is inside the call to super dealloc, in UIButton -> UIButtonContent dealloc. I assume I am doing something poor with my memory management like deallocing twice but I can't spot where.

Is what I am doing by loading the nib multiple times legal?
