a5a2c3c by Peter Wu (peter@xxxxxxxxxxxxx):

    Fix infinite loop for when port max range is -1
    
    Due to integer overflow (unsigned -1 + 1 = 0), a call to
    dissector_add_uint_range would be stuck in an infinite loop, eventually
    crashing due to out of memory.
    
    Found when setting radius.alternate_port:-1, but could happen with any
    dissector using similar ports_range constructs.
