Is this row level check really useful? Because I think if we check the bound every line the performance may not be very well.
I think we could add the bound check at line 282, it is enough?

This check is made to ensure that each index *it is less than src_size before accessing src[*it] - the UT attached simulates this error condition and hence this check..please let me know your thoughts
