The linker generates an executable anyway and it _seems_ to work. However, I observe infrequent crashes of the application that I don't observe on a machine where I built Boost and the application (without any warnings) with gcc 3.4.2 / ld 2.14.90.0.5. Thus I suspect that the warning is there for a reason and points to the problem causing the crashes.
What version of the binutils are you using on the machine where things behave badly?
GNU ld version 2.15.91.0.2 20040727 (SuSE Linux)
If its not at least as new as 2.14.90.0.5, can you upgrade? Problems like this often stem from binutils bugs in my experience.
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.
