Summary: Bug: CMS Swap
Initial Comment:
In Version 1.1 the CMS Swap does not work correctly. The problem is located in the constructor
BlackVanillaOptionPricer::BlackVanillaOptionPricer(Rate forwardValue,
Date expiryDate,
const Period& swapTenor,
const boost::shared_ptr<SwaptionVolatilityStructure>& volatilityStructure )
where the member variable smile_ should be initialized with the result from volatilityStructure_->smileSection(expiryDate_, swapTenor_).
As far as I can see inside the function volatilityStructure_->smileSection(expiryDate_, swapTenor_) everything is constructed correctly.
But as soon as the result is copied into smile_ some of the data are not set.
In particular the variable exerciseTime_ is a huge negative number causing an error later on.

Message:
Weird. The result shouldn't even be _copied_ into smile_; only a pointer
to the smile section should be copied.
Do you have some code that reproduces the problem?

Message:
Even in release mode the results are not convincing. Recomputation of a
cms-swap produces two different results. The cashflow table of the CMS-Leg
is completely wrong.
