Refactored & fixed.

Reoccuring segfault that happens seemingly with very minor changes (was happening earlier with the SSSP application as well). Need help debugging and verifying it happens on Linux-based machines as well and not just in my version.

Still need help with this, if @crozhon has time, any pointers will be appreciated! I am not even sure where the error is. One thing I can do better is maybe to remove the style changes from actual changes to make the diff easier to read.

Commenting out main in kcore.cu let me find this issue. Now it's giving normal compiler errors for you again (something about frontier_t being undefined). Hope this helps.

HUGE! I'll take a look at it again. Thank you so much! How did you figure out that was the issue? Any compile-time debugging tricks or just reading through the code?

I built with test_kcore commented out, and it pointed to that error in kcore.hxx. I think maybe it hitting multiple compiler errors caused the segfault, so getting rid of the frontier_t error fixed it? Not sure. Maybe it occurred as part of printing the error?
