To fix you problem, check the return value of fopen(). If you can't open the file it returns NULL and puts a reason into errno. You can get the error message string with strerror(). Consider using perror() to output the error message as you loop through the files.
There's other possibilities like not handling really long lines, but this is by far the most likely problem.
This doesn't get the executable, but fixes the general segfault problem you're having which is a much more reasonable thing to do anyway.
