The Vuforia samples do not crash.

If I understand correctly you have a sample that integrates CloudReco and Image Targets?  

This should work, so it would be helpful if you could provide more details on what you are doing and how you have put everything together.

Also, are you able to reproduce this crash using the basic CloudReco and adding an Image Target into the scene?
