GNU ld version 2.15.91.0.2 20040727 (SuSE Linux)

In the meantime I found that the crashes were not related to the linker
warning; I eventually found that I miscalculated some index into a vector
which caused the crash. Once I realized that I was able to reproduce the crash
on both machines.

Nevertheless, the linker warning makes me uneasy... Will the application crash
as soon Boost.Serialization needs to throw? If I read the warning correctly
then the reference to boost::archive::archive_exception::what() points to
nowhere because the linker discarded the corresponding code section.
