Description
New python function sig code breaks this test case (gcc-4.1.2):
#include <boost/shared_ptr.hpp> #include <boost/python/module.hpp> #include <boost/python/def.hpp> #include <boost/python/class.hpp> #include <boost/python/init.hpp>
using namespace boost::python;
struct base {}; struct concrete : public base {};
struct Test {
Test (boost::shared_ptr<base> _x) : x (_x) {} boost::shared_ptr<base> x;
};
BOOST_PYTHON_MODULE(test1) {
class_<base, boost::noncopyable> ("base", "abstract", no_init); class_<concrete, bases<base> > ("concrete", "concrete"); class_<Test> ("Test", init<boost::shared_ptr<base> >())
.def_readonly ("x", &Test::x, "x") <<<< this seems to trigger the error
;
}

This is most likely related to Nikolay Mladenov's changes from early September. I just alerted him to this issue. Ralf
