I can't find out if it has been tested on 10.6 yet, but it's certainly been tested on the gcc version that comes with it. There are no signals involved, only standard C++ exceptions which are delegated to Python exceptions. Is it possible there is any C++ code linked to this that was generated with another compiler version?
