This is expected as flyweight<> default factory is based on Boost.MultiIndex,
which is not supported on Borland. You might try redefining your flyweight
where the factory is based on a regular std::set. I don't know if this will work
in Borland, though, I haven't tried this compiler myself.

Are you compiling in C++/CLI (CLR) mode rather than pure C++? This
might be the cause of the speed penalty and the crash. I don't know how
compatible the library is with managed C++'s. If you can provide me with
a complete test program I'll be happy to try it myself this afternoon
(in ~10 hours) and report my findings.
