Just to let you know, I do not see the same behavior (I have cleaned up the
code and added the header files).
Here is the compilation command and output I get:

>g++ test.cpp -otest -lboost_serialization
>./test
serialize: 0.11
serialize: 0.12
serialize: 0.11
serialize: 0.11
serialize: 0.12
serialize: 0.11
serialize: 0.12
serialize: 0.11
serialize: 0.12
...
