bondhelpers.cpp bug

Hi folks,

The constructor for the FixedRateBondHelper class that takes a bond as a parameter doesn’t instantiate member variable ::bond_ before use.

Either the input bond should be used (if it is assumed that the bond will not be used elsewhere) or a copy of the bond should be created for specific use with the yieldtermstructure.

Currently, neither solution is perfect:

a)       If a copy of the bond is created, then for a derived class (from FixedRateBond) to work, we’d also require a FixedRateBond::clone() method.

b)       If we use the input bond, there’s no guarantee that the bond is not used elsewhere with a different yieldcurve which would lead to uncertain results.
