67cbafa by Martin Kaiser (wireshark@xxxxxxxxx):

    remove unnecessary integer overflow checks
    
    ... and don't call THROW() from a dissector
    
    If we have a guint32 a and interpret 2*a as gint, we'll always end up
    with a negative value if 2*a overflows. Both tvb_get_string_enc() and
    proto_tree_add_item() handle this case and throw an exception.
