    The current EXTBAS has SI:EXTEND-LENGTH subr defined as
    (defun si:extend-length (x) (si:extend-length x))
    or something equivalent, expecting a macro definition for si:extend-length
    to come in from EXTHUK.  It did, but after that SI:EXTEND-LENGTH was 
     own-symbol'ified, leading to a short inner loop on si:extend-length
    tail recursing to itself, but not terminating in finite time.
This hasn't been fixed yet -- so I fixed it merely by removing the
OWN-SYMBOL declaration in the EXTBAS file, and recompiling.
