De-serialization of shared_ptrs derived from enable_shared_from_this fail

[Carus V. (Bud) Clarke <carus.v.clarke@…>]

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,

I'm having problems with test_weak_ptr_serialization.tgz - could you send a *.zip file version?

I've run you example and found it to fail. Then I included your patches and the example ran. I confess, I really didn't analyze your code carefully. I just assumed that anyone who goes into that area knows what he's doing. Could I ask you one more favor? Could you tweak the test so that I can add it to our test set? That is, it should return success if it passes. Also it would be nice if it did some BOOST_TEST_? macros to document what the expected results are. Look at the other tests to see how this is done.

Thanks for this.
