Thanks Antoine :) It was the line "it's the way integer division by zero, which is undefined behavior, manifests on the particular implementation" that led me to find the flaw (one of my indices was out-by-one). Interesting it's called "Floating point exception" when it's an integer operation that causes it, but as the person who posted that rightly said, it's a misnomer.

It crashes, giving "Floating point exception" in the terminal. Can anyone tell me what this means, and what I should be looking for in the code, to fix?
