Segmentation fault when assigning "back" button

[elbunuelo]

I've just compiled ES-config in my Fedora 20 machine and I'm getting a segmentation fault when it asks me to assign the "back" button.

Some stuff worth noting:

• Had to add -lpthread to the makefile LIBS variable so it would compile.
• I've tried both with a PS4 controller (connected by USB) and a keyboard.

Let me know if/how I can provide more information about the error.

Need to Debug the Code.
