[C++-sig] pyste and compressed_pair

[Dmitriy Morozov]

Hi,

If I have the simplest header file that includes compressed_pair.hpp,
and I run pyste on it, pyste crashes complaining about is_abstract.hpp
included from compressed_pair.hpp. An example and error messages are
below. I was wondering if this was a known problem, and if there are
any workarounds. I'm trying this right now with Boost 1.36.0, but I
believe the same problem occurs with 1.37.0 (I tried it earlier).

Thanks in advance for your help.

test.h:
#include <boost/compressed_pair.hpp>

struct A
{
    int a;
};

test.pyste:
Class("A", "test.h")

When running "pyste.py test.pyste" I get:
