It is only for libsvm train vector classifier. When the option parameters optimization is enabled, the trainer tries to optimize but without stopping (the process is performed again, and again like a loop without ending with the confusion matrix), whatever the kernel used (same issue for rbf, polynomial, sigmoid and linear). I don't know which new code has been written since 6.6.0 and that could explain this bug. I have also noticed that this issue appears on both windows and linux systems.
