[FAIL] LinkAllRegressionTest.Pasteboard_ImagesTest : a - length 

[spouliot]

It does not seem to be linker related. We set the a value...

UIPasteboard.General.Images = new UIImage[] { img };

but we get an empty array back. All instances are looking fine

UIPasteboard.General.HasImages returns true :|
looks like an Apple bug
I'll adjust the test then file a radar/feedback

Fixed with #6264 merge

keeping open as I still need to report it to Apple feedback with an ObjC sample
