[Insight-users] Got an error "Optimizer stop condition = LBFGSBOptimizer: Failure" when ran DeformableRegistration8 in ITK v4

Hi all,

        When I ran DeformableRegistration8 in ITK v4, I got output message
like this:

*Optimizer stop condition = LBFGSBOptimizer: Failure*
          Probe Tag    Starts    Stops             Time (s)
        Registration           1            1           1119.09
          Probe Tag    Starts    Stops           Memory (kB)
        Registration           1            1            419332

The application stops and throws an error "*LBFGSBOptimizer: Failure*". In
the source code of DeformableRegistration8, I set the parameters of
optimizer such as "convergence factor" as this:
  optimizer->SetCostFunctionConvergenceFactor( 1.e7 );
  optimizer->SetProjectedGradientTolerance( 1e-6 );
  optimizer->SetMaximumNumberOfIterations( 200 );
  optimizer->SetMaximumNumberOfEvaluations( 200 );
  optimizer->SetMaximumNumberOfCorrections( 5 );

Except the code above, I didn't change any code else. I have no idea what
happened. Any suggestion would be appreciated.

By the way, there is some information about my PC in case this would be
inportant:
Processors: Intel(R) Xeon(R) CPU E5630 2.53GHz 2.53GHz (2 processors)
RAM         : 48 GB
OS           :  Windows Server 2008 R2
