What version of Clisp? I just ran the tip of the 5.16 branch with clisp
2.44.1, and clisp has no unexpected errors. (I do get a warnings about
simp-unit-step and simp-pochhammer being redefined, though, in rtest14.)

What version of CMUCL? Using cmucl 2008-08, no unexpected errors were
found. IIRC, you were using a rather old version of cmucl which gives
an error or something about raising 1^<bignum> which was fixed a long
time ago.
