Well... OSX is using g++ and libstdc++, right? I've seen this bug a
lot of times and I've even documented it in the README:

"... if gcc is used as the compiler, libstdc++ version 4.5 or later is
required at runtime. This is due to a bug in earlier versions of
libstdc++ that sometimes makes dynamic_cast fail under conditions
where it should not."

In other words, your version of the standard C++ library is buggy and
there is nothing that can be done about it except for upgrade. Sorry.
