[C++-sig] Extracting and returning a c++ object from python and garbage collection

[William Ladwig]

I looked at the Py++ code and tried it out (it's similar to how I tried it originally) and it also throws a "dangling pointer" exception from the interpreter.  I was able to keep it from crashing by extracting a ReqInput reference and then creating a new ReqInput by copying the extracted one.  It's not very efficient unfortunately, but it might be the only way to do this.  Thanks again for your help.


std::auto_ptr<ReqInput> convToReqInput()
{
        object py_ob = this->get_override("toMapleInputArray")();

        ReqInput& r_arr = extract<ReqInput&>(py_ob);

        std::auto_ptr<ReqInput> r(new ReqInput(r_arr));

        return r;
}
