This problem is most likely not CLion's fault, but it doesn't really help much with finding the root cause either. I could observe this behavior with one specific project of mine, and it affects CLion versions 1.2.4 and 2016.1. When I load this project on a VM with Ubuntu 15.10, CLion begins to build the symbols. It quickly uses up all CPU available, and continues to do this for ~2 minute, then CLion just crashes. When it had been started from the command line, it streams the word 'Killed' onto the console.
That same project loads fine on a VM running Ubuntu 14.04 LTS, and on a PC running Ubuntu 15.10.
So it is clear the problem has to do with the environment. What can I do to figure the exactly reason for this crash out? I looked for logs or dumps, but could not find any.
