Hello Robert, Thank you for your quick reply. Today I down-loaded and rebuilt boost 1.61.0, for both .zip and .7z versions from boost.org but I still see that final expanded line. Regards Colin Humphries On 6/26/16 3:33 PM, Colin Humphries wrote:

After converting to boost 1.61 and Visual Studio 15 we now see a

problem closely related to one reported in ticket #12141. Our XML

archives now end with the following 2 lines:

</boost_serialization>

</boost_serialization>

Could someone suggest a quick fix please? I think the problem must be

in archive/impl/xml_woarchive_impl.ipp but I cannot grasp how

the archive destructor emits the last line.

When this was reported we took emergency action to make sure it was addressed before the final release. Are you sure you have the actual 1.61 final release? Robert Ramey
