Thanks,

I cannot reproduce this bug here. How often can you trigger this error? 
Only once, or every 10th invocation, or ...

I have modified the script a bit and ran the following command in octave 
without any errors.
for i=1:1000, test_cf2,end

This was with gnuplot4.2.2 and the current gnuplot-cvs. In addtion I 
tried the x11 and the wxt terminal - no problems as well.
