 De-serialization of shared_ptrs derived from enable_shared_from_this fails
 to initialize the base enable_shared_from_this objects, which causes a
 program crash when shared_from_this() is called.  The root cause seems to
 be that a shared_pointer<void> is created inside file
 shared_ptr_helper.cpp, instead of a shared_ptr<T>, with T being the
 original class.  This causes the non-enable_shared_from_this constructor
 to be called.  I worked around this by moving the initial construction of
 the shared_ptr to file shared_ptr_helper.hpp.

 A patch file is attached and also a test program, modified from one
 originally written by Alexander Gutenev.

 Thanks,

 Bud Clarke
