Dear Octave developers,

If I execute the code below, sometimes I get an unexpected error:


octave:1> load octave-condest.mat
octave:5> condest(A)
error: S(_,4): but S has size 8x3
error: called from
    normest1 at line 202 column 13
    condest at line 227 column 21


I have attached a test script, which can be used to reproduce the error.


octave -f octave-condest.m


If I run it, I always get the message 

condest failed at step 3
