[ITK] LBFGSB Issues

[Matt McCormick]

Hi Toby,

> 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.

Please consider submitting a patch [1] that addresses this in its C
counterpart [2].


> 2 - Is the LBFGSB optimizer thread-safe? I suspect not as I am getting segfaults in my multi-threaded program.

I don't think so :-(


Thanks,
Matt
