Varnishstat: bandwith usage

I have a question about measuring bandwith usage with varnishstat.
I would expect 'Total header bytes' and 'Total header bytes' to be
the total number of bytes sent to clients since varnishd was started?
Measuring these numbers at different points in time could therefore be
used to calculate the bandwith usage. So here are my measurements:
* Initial values:
556874988 Total header bytes
20238688347 Total body bytes
* 75 minutes later:
848969031 Total header bytes
30800272652 Total body bytes
The problem is that the correct values are 40 times larger
than what I get from varnishstat. So is this a bug in varnishstat?
I notice that the total body bytes is larger than 2^32, perhaps there is
an integer overflow somewhere? Or am I interpreting these values wrong?
