The example code for using getline fails to initialize "line". If I run the following code through valgrind:
    

    #define _GNU_SOURCE
    #include <stdio.h>
    #include <stdlib.h>

    int main()
    {
        size_t n = 0;  char *line;
        while (getline (&line, &n, stdin) != -1) {
            fputs (line, stdout);
            free (line);
            n = 0;
            line = NULL;
        }
        free (line);
    }


then valgrind prints the following message:

==3587233== Conditional jump or move depends on uninitialised value(s)
