thallium | A simple , extensible JavaScript test framework | Unit Testing library

I wanted to return the name of elements based on two conditions; even protons number and odd neutrons number. I've tried to print both tests and it turns out well. However, when I try to print the elements using 'and' logical, an error has occurred due to different broadcasting. I can't figure out how do I reshape it. Help me out.

The elements, protons and neutrons.

I've already converted elements, protons and neutrons into arrays.

The input;

Here is the code i already attempted but it didnt work out:

This code is made by a 14 year old boy (me) so dont worry about the maintenance.

HTML:

So I've been working on this program for a while and I have gotten it to a point where it compiles just fine but when I run it I get a Segmentation Fault. I've backtraced the fault via gdb to the function below but cannot for the life of me see where the problem is, and I am not versed enough with gdb to determine any more details on the origin of the fault. Like the question says I'm trying to read from a file into a dynamically allocated linked list where each node of the list has a pointer to a struct called Element. Then I need to convert that linked list to an array of pointers to struct Element. I hope that a fresh pair of eyes can see some mistake I've made that I have been blind to.

UPDATE: Added rest of source files. Added gdb backtrace snippet.
