I tried for 6 weeks. Eventually, it just stops functioning. The same program and arguments spits out "segmentation fault" 33% of the time I run it, with the other 67% working perfectly. The only way I could explain it was that it was in a function outside the main, because when I put the exact same code in the main, compiled and ran, it worked.
I have no other explanation. At some point, having too many nested loops and variables causes segmentation faults, whereas less complex code functioned without error. I needed to have certain things performed, and it only functioned in the main.
