[C++-sig] boost python exception handling

[Austin Bingham]

Hi Ryan,

I tried out your code (g++, python2.6, boost-1.40) and it worked just
fine. However, I had to make a few changes to your compilation command
to get it working. The python module you're defining is called
"testing", but your command is generating a "libclassical.so"; you
need to output "testing.so" (no leading 'lib') for python to import
it/associate it with the module "testing". Is it possible that you're
actually loading a module from some old build or something?

Other than that, I can't see any problems. Can you possibly post a stack trace?

Austin
