478	Serialization 1.33 assertion failure when deserializing STL 	tzlaine	Robert Ramey	"{{{
I am seeing an assertion failure in
reset_object_address.  The assertion output is:

/tmp/boost_cvs/libs/serialization/src/basic_iarchive.cpp:266:
void
boost::archive::detail::basic_iarchive_impl::reset_object_address(const
void*, const void*): Assertion
`object_id_vector[i].address >= ol
d_address' failed.

These are the values in the failed assertion:

i == 1
object_id_vector[i].address == 0x43ef0920
old_address == 0xbfffe240

For good measure, new_address == 0x43ee7830 and this ==
0x43eeffc0 at the point of failure.  I don't know if
that indicates that old_address is garbage, or if it is
supposed to be that far away from the other addresses.

This is the same assertion failure reported in bug
#1262084, but I am not using polymorphic archives.  I
verified that the test code submitted for that bug
fails for me as well, but when I converted it to
non-polymorphic archives, it works fine.  Therefor I
have no idea if these bugs are related.

The code producing the failure worked fine under
version 1.32.

Unfortunately, the code that produces this failure is
pretty involved.  All my attempts to produce a minimal
set of code that provokes the failure have failed.  The
object producing the failure is being serialized
through a pointer-to-base.  The inheritance of the
object's class is Wnd -> Control -> TextControl.  The
object within the TextControl that is actually
producing the failure is m_line_data, which is a
std::vector.

I have two fairly minimal serialize methods that I have
created for the object being loaded when the failure
occurs -- one of which works and on of which does not.

Method A works:
template <class Archive>
void GG::TextControl::serialize(Archive& ar, const
unsigned int version)
{
    ar  & BOOST_SERIALIZATION_NVP(m_line_data);
}

Method B fails:
template <class Archive>
void GG::TextControl::serialize(Archive& ar, const
unsigned int version)
{
    ar  & BOOST_SERIALIZATION_BASE_OBJECT_NVP(Control)
        & BOOST_SERIALIZATION_NVP(m_line_data);
}

Below is the stack at the point of failure.  I Hope
this helps.
