EXC_BAD_ACCESS on accessing UIImage's size property

The image is an instance of UIImage. The first line executes with no problems, but the second one gives an EXC_BAD_ACCESS error at runtime.

NSLog(@"SCALE: %f", image.scale);
NSLog(@"TEST: %@", NSStringFromCGSize(image.size));

I can view the values of size property in Xcode by mouse-hovering it though.

enter image description here

Can you please help me in understanding what's wrong with it and/or what I might be missing?

Tested on a device and in simulator running iOS 8.

UPD: This is how I'm creating the image:

ALAssetRepresentation *rep = [asset defaultRepresentation];
CGFloat scale  = 1.0f;

CGImageRef imageRef = [rep fullResolutionImage];
UIImage *image = [UIImage imageWithCGImage:imageRef scale:scale orientation:(UIImageOrientation)rep.orientation];

CGImageRelease(imageRef);

I just tried to delete the last line CGImageRelease(imageRef); and it seem to be fixed the problem. But I do need to release the CGImageRef, since I'm loading very large photos inside a loop and that takes a lot of memory.

So, I figured it out. The problem was that I released a CGImageRef that I didn't own.

CGImageRef imageRef = [rep fullResolutionImage];

If you get a CGImageRef by calling fullResolutionImage, you don't own it. Therefore, you don't need to release it yourself neither.

CGImageRelease(imageRef);

Removing the last line fixed the problem for me.
