10348	Compilation failure in shared_ptr_helper.hpp	gary.mirams@…	Robert Ramey	"As part of the Chaste simulator (https://chaste.cs.ox.ac.uk/trac) we use boost serialization, and test compatibility with multiple versions of Boost (1.40-1.55 inclusive). 

We tested it out with the new boost 1.56, but got the following compiler error:

I fixed this with two new boost #includes in `boost/serialization/shared_ptr_helper.hpp`, to include files in the serialization library that are mentioned in this file, but not #included.

So I've submitted a pull request on github to fix it.

(sorry, trac wouldn't let me create a ticket with links to the pull request)"	Bugs	closed	Boost 1.57.0	serialization	Boost 1.56.0	Problem	fixed
