Re: [Quantlib-dev] RelinkableHandle<YieldTermStructure> reset to Null

[Luigi B. <lui...@gm...>]

It looks like the spreaded curve notifies its observers of the change,
one of them tries to perform some calculation as a consequence, and
the calculation fails because the handle is empty.  Can you reproduce
the problem in a short program you can post?
