[boost] [pending] fibonacci_heap -- not working

Hi, is there anybody out there using the fibonacci_heap.hpp? I have a working implementation of dijkstra's shortest path algorithm and was trying to use fibonacci_heap from boost/pending to optimize its performance. To me it seems that it is not working properly. A key feature of this structure is that it should be possible to mix 'pop' and 'update' calls -- but, unfortunatly, after the first call to pop I get arbitrary indices from the heap. Some are even popped more than once. I am using the most recent CVS version. Can anyone help me here? Thanks in advance Florian
