There is remaining this issue of the elfutils unwinder. It seems a proper fix catching all infinite backtraces is not possible under the constraints for the patch acceptance from this mail thread so asking for verification if the constraints above which I deducted from the mail thread are the ones required for the patch acceptance so one can write down at least a partial fix of the problem. Thanks, Jan
