Summary: segfault and out of memory?

Initial Comment:

My system is a linux has 2GB memory and 4GB virtual 
memory. The segfault occurred when my program only 
requested around 1GB memory. (I monitored this using 
top command.) My system should be able to handle my 
program since it has a total of 6GM memory. 


The core dump says:
  vacall: va_start type %d and va_return type %d 
disagree.
  vacall: struct of size %u too large for pcc struct return.
  trampoline: Out of virtual memory! 


To simulate the effect, I wrote this small program to 
reproduce the problem. 

[2]> (defun test (n) 
  (let ( (x nil) ) 
    (setq x (make-array n :initial-element nil))
    (dotimes (i n)
      (setf (aref x i) (make-array 10 :initial-element nil))
      (if (equal (rem i 1000000) 0)
	  (format t "done with ~A iter~%" i))
      )
    ))
[3]> (test 10000000)     // 10^7
done with 0 iter
done with 1000000 iter
done with 2000000 iter
done with 3000000 iter
done with 4000000 iter
done with 5000000 iter
done with 6000000 iter
done with 7000000 iter
done with 8000000 iter
done with 9000000 iter
NIL
[4]> (test 1000000)       // 10^6
done with 0 iter
Segmentation fault

Is there a maximum memory limit?
What can I do to increase the memory in clisp?

thanks

Ben B.
