Re: Segmentation Fault with PuTTy

So, I gave this some thought, and I believe you are creating objects outside of your robot class. At the moment, HALInitialize is not called until after wpilib.run() is called, and if you try to create a device before HALInitialize is called, it will segfault.

For the moment, create your devices inside your robot object, and the segfault will go away. In the next release of the RobotPy WPILib libraries, it will raise an error if you do this.
