[Boost-users] [Serialization] #include order

Hi all,

Compiling the following program with Boost 1.42 fires an static assertion in
boost/serialization/shared_ptr.hpp:153. This is expected.

But if I change the order of includes (compile with -DCHANGE) the assertion
fires in boost/serialization/shared_ptr.hpp:121. The assertion is expected
but I found it strange that I end up compiling a different part of the same
file...

The code in that section seems related to serialization of shared_ptr in
version 1_32, but since I'm not able to understand the difference, I'm just
reporting it in case the order of #includes might affect how shared_ptr's
get serialized.

Regards
