[ITK] LBFGSB Issues

[Wood, Tobias]

Hello,

I am trying out the LBFGSB optimizer. I have two issues (ITK 4.7.2, using the “itkLBFGSBOptimizer.h” header)

1 - I think I am hitting this bug that scipy also had trouble with: https://github.com/scipy/scipy/issues/2261 It is annoying, as lots of text is printed to the screen, but not show-stopping.
2 - Is the LBFGSB optimizer thread-safe? I suspect not as I am getting segfaults in my multi-threaded program.

Thanks,
Toby
