Synopsis: gcc fills variable with random data

State-Changed-Why:
    This is the kind of thing to be expected when you invoke undefined behavior.  After c=-1, result[c++] indexes result[-1], and then increments c.  -1 is not a valid index into result.  From that point on, all bets are off.  Perhaps you meant result[++c] ?
