<shrug> I have no idea. It's bog-standard C, and it works just fine here.
If you think the program is broken, perhaps you'd care to explain what
rule of C you think I've breached?

My timings with a 17993728-byte input file are as follows:
C: 1.33 seconds
C++: 1.44 seconds
Java: 17.59 seconds
and all three programs give the same result (which is obviously different
to yours, because I used more data). Since the original input file was
1000 lines totalling 500 each, I would expect the answer for my data
(which was 4096 times as big) to be 4096 * 500, or 2048000, which is
indeed the result given by my C version, my C++ version, and the site's
Java version.
