You may need to reproduce the scenario that occurs in Boost.Python.
Two shared C++ libraries (extension modules) are loaded by the
application with dlopen.  Each of these libraries links dynamically in
the ordinary way to the same C++ library (Boost.Python).

You can reproduce the problem by running

  bjam try

in

  libs/python/test
