I do not pretend that I understand the inner workings of the serialization library, but this broke code which used to work with release 1.53.0, so something has changed. Do you mind either pointing to me where to find the implementation of basic_xml_grammar in the source code distribution (in which case I will take care of finding out what went wrong with the linker locating the code) or if the implementation is really missing then providing it (if that were the case could you provide it before the next release -- I would like to not wait till then). Thank you." Bugs closed To Be Determined serialization Boost 1.59.0 Problem invalid epsilonomega2k@…
