1    int a[10000];
2
3    void f()
4
5        {
6        int i;
7
8        for( i = 0; i < 10000; i++);
9             a[i] = i;
10       }

This function is supposed to initialize a global array, but something isn't working. Can you or your compiler see the problem?

Reference Manual Explanation

 
722    Suspicious use of ;  -- A semi-colon was found immediately to the
       right of a right parenthesis in a construct of the form while(e);
       or for(e;e;e);.  As such it may be overlooked or confused with
       the use of semi-colons to terminate statements.  The message will
       be inhibited if the ';' is separated by at least one blank from
       the ')'.  Better, place it on a separate line.
