Forgive my ignorance, but what exactly is a seg fault?

Benoit

It means a program is trying to access memory outside it's address space, usually out of bound references

Specifically though SegFault tends to happen in Linux based operating systems, and probably a few others. In Windows you will get an error called an "Access Violation" or an "Illegal Operation", never a Segfault.

Segmentation fault happens when the Operating system gets pointed to a confusing or non existant address on return from a subroutine or actually returning to the operating system itself.

For example, when a program calls a subroutine, on the stack, a special note is pushed, the RET address. Segmentation fault happens when the OS tries to read the RET point, and when it goes to the address an RET address specifies it doesn't exist in memory. So, segmentation fault is called. And the program is exited.

I could have explained it more in depth, but you should get the general idea.
