Fwd: Boost version

Posted by Peter Caspers-4 on

but ... does that nevertheless point to a problem with the copy
constructor of PiecewiseYieldCurve ?
which is probably not very relevant, still we could disable it (and
the assignment operator) for safety reasons ?

oh, sorry, it should rather be

    boost::shared_ptr<YieldTermStructure> yts2 =
        boost::make_shared<PiecewiseYieldCurve<Discount, LogLinear> >(
            0, WeekendsOnly(), isdaRateHelper, Actual365Fixed());

and this indeed works.

Hi Luigi,

I try to use boost::make_shared to create a shared pointer to a
PiecewiseYieldCurve. I thought code like

    boost::shared_ptr<YieldTermStructure> yts1(
        new PiecewiseYieldCurve<Discount, LogLinear>(
            0, WeekendsOnly(), isdaRateHelper, Actual365Fixed()));

should work similar to

    boost::shared_ptr<YieldTermStructure> yts2 =
        boost::make_shared<PiecewiseYieldCurve<Discount, LogLinear> >(
            PiecewiseYieldCurve<Discount, LogLinear>(
                0, WeekendsOnly(), isdaRateHelper, Actual365Fixed()));

Yet while the first variant works fine, the second variant throws an exception

terminate called after throwing an instance of 'QuantLib::Error'
  what():  not enough points to interpolate: at least 2 required, 0 provided

Do you know why or what I am doing wrong ? I attach the complete
example. The output I get from this is

setting up discount curve
test discount variant 1 = 0.980123
terminate called after throwing an instance of 'QuantLib::Error'
  what():  not enough points to interpolate: at least 2 required, 0 provided

Thanks
Peter
