The use of the unsigned variable 'i' as a loop index leads to the test for i being non-negative always being true. Instead declare 'i' as an int so that the for loop will terminate as expected. If the original for loop completes 'i' will be 1 past the end of the array so decrement it in the subsequent error path to prevent an out of bounds access occurring. This issue was found by Smatch.
