    Excessive gas .irpt count
    
    There is a test in do_repeat to error on "negative" repeat counts.
    Just at what value a ssize_t is negative of course depends on the
    host.  Change the excessive repeat count to a fixed value, 0x80000000,
    ie. what would be seen as negative on a 32-bit host.
