Clisp & Bessel function errors, was: Maxima 5.16.1 release



I have installed CLISP 2.46. 

Bessel tests passes, but not rtest_taylor.mac. 15 problems fail. And when I do
this file within run_testsuite() I get a fatal error and my computer reboot.

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.
