I am using boost graph library. I can serialize the graph successfully. But
when deserialized a graph from the file, an unsupported version exception was
throwed out.  I created a minimum runnable example and posted it [here]
(http://www.rapidshare.com.cn/Bq95n2v). The serialized graph file is enclosed
as well. The file is generated with the same version of graph library. Could
anyone help me to find the problem? thx!
