Description of problem:
Creating a matrix with eye(n) and then doing an rref() on that matrix causes octave to crash complaining about a corrupted doubly-linked list.  Sometimes it backs out nicely.  Other times, a kill -9 is in order on the PID.

Version-Release number of selected component (if applicable):
$ rpm -qa | grep octave
octave-3.2.4-2.fc13.x86_64
$ rpm -qa | grep glibc
glibc-2.12-1.x86_64
glibc-common-2.12-1.x86_64

How reproducible:
Always, but error messages change for no apparent reason.  A crash always ensues.  

Steps to Reproduce:
1. Load octave command line prompt.
2. Execute the following:
A=eye(6) [enter]
A  [enter]
rref(A) [enter]
exit [enter]
(Crashes here)
  
Actual results:
octave crashes

Expected results:
Return the identity matrix as it is already in simplest terms.
