I doubt the error lies in a system-included header file. That just seems off to me. A possibility is you're trying to sort something from a file that doesn't exist, as pretty straightforward. Or, possibly, data is being culled from a non-existant source. (I've never used/looked at/seen how qsort works, sorry. Just offering a conjecture).
