    Hi Dennis. I get the same error and am testing a correction right
    now. The problem is related to improvements to boot2 in r233374
    (MFC of r232570 and r232754). It has the side-effect of making the
    binary just a wee too large for the BTX link to succeed. r232754
    contains a change not MFCd to stable/9:

    It's likely this with get it shrunk down enough.
