     Hmm.  I can't reproduce that with a clean checkout, even with
     `make -f Smake check'.
     I'm on x86 (32 bit) GNU/Linux.

Me too.

What version of math library do you have?  One machine where the
problem manifests itself has 

ls -l /lib/ 
lrwxrwxrwx 1 root root 13 2006-04-10 20:37 /lib/ ->

another machine which doesn't give this error has

ls -l /lib/ 
lrwxrwxrwx  1 root root 13 2005-12-01 09:12 /lib/ ->

I'm not sure what all the columns mean in
tests/expressions/randist/chisq.out.  Can we add an explanation somewhere?

Is the 5th column the probability? If so, then my book of tables tells
me that Chi-Squared for 2 degrees of freedom and p = 0.01 is indeed
9.21, in which case the test is wrong, and for some reason my machine
is the only one computing the value correctly.

Maybe Jason would like to comment on this.
