Description
Using the sample code in http://pointclouds.org/documentation/tutorials/bspline_fitting.php#bspline-fitting
And using this data as an input PCD file :
https://drive.google.com/file/d/0B7IfWv6WuKo8UHhqaFhHR2pBblk/view?usp=sharing
The program freezes on "surface fitting..." and never return anything nor error message.
The PCD file's point looked like this, which should not be a problem for B-spline to fit to? :
I am on Ubuntu 14.04, build PCL by myself from GitHub code. (To enable on_nurbs module)
Computer is Macbook Pro 13 inch latest model (with Force Touch touchpad), no dedicated GPU.

Research direction
Start with the B-spline fitting tutorial and the initNurbsPCABoundingBox function, then reproduce the freeze using the linked PCD file on Ubuntu 14.04. Compare the behavior at “surface fitting...” and determine whether fitting completes or reports a diagnosable error; done means the supplied input no longer hangs without explanation.
