[C++-sig] boost::python and exceptions, seg fault

Hello,

I've pulled some of my hair out over this.  I can't seem to get
Boost.Python (from Boost 1.29.0) to handle exceptions.  Instead, they
seem to cause the python interpreter to abort.

A very simple example is below, along with a backtrace.


cd .../boost_1_29_0/libs/python/test && bjam ... exception_translator.run
runs to completion.

Any clues would be much appreciated!
