At safety 3 this function compiles just fine.  At safty 1 I get an
error earlier, in DFLOAT.lsp I see:

(DEFUN |DFLOAT;base;Pi;7| ($)
  (PROG () (RETURN (FLOAT-RADIX '#<OBJNULL>))))


Now, #<OBJNULL> is IMHO very strong indication of memory corruption
(I see no legal way to produce it).  OTOH the vector (value of '#1')
you see is clearly wrong in this place, but it looks like normal
Axiom domain vector.  So ATM it not clear if both failures are related.
