    I suspect some kind of hardware error.  That bogus argument,
    #<DTP-PACKED-INSTRUCTION-77 37777777777> looks like something with all
    its bits on (38 of the 40 bits in a word are evident from the numbers in
    the printed rep, but I don't know the internal tag for
    DTP-PACKED-INSTRUCTION offhand). [...]

Yipes!!!  Any tagged computer architecture in which all-ones is a valid
datum scares me.  (Likewise all-zeroes.)
