0fbb5f8 by Guy Harris (guy@xxxxxxxxxxxx):

    Do bounds checking of the offset and length in proto_tree_add_string().
    
    Throw an exception if they don't correspond to data available in the
    packet - and do so even if the protocol tree argument is null, so that
    we catch very long strings that could cause the offset to overflow.
    
    Ask why we try to handle a null pointer passed as the string argument,
    while we're at it.
