[C++-sig] boost.python program crash Python interpreter at exiton Fedora 8

[Tang, Guang]

Thanks for your reply.
My application wraps a bunch of c++ classes to Python, the building process is managed by CMake.
To simplify the problem. I replace one of the wrapped class to Hello class in the tutorial of boost.python. But I still get this segfault at exit.
