I've attached a tgz file with four files demonstrating the problem:

     If I use dlopen() and dlsym() to get a pointer to a global function in
     a C++ library, the thing dumps core when I call it.

     If I use excatly the same procedure when it's a C library, everything
     is fine, and a small message is printed to the screen.

I would be _very_ happy, if you can find some reason why this doesn't work.
