Hi Ben 
unfortunately no change:

*********************************************************
error: Invalid call to strcat.  Correct usage is:

 -- Function File:  strcat (S1, S2, ...)


Additional help for built-in functions and operators is
available in the on-line version of the manual.  Use the command
`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW
at http://www.octave.org and via the help at octave.org
mailing list.
warning: __gnuplot_get_var__: some elements in list of return values are undefined
***************************************************************

however checking the memory consumption I suspect some 
leakage memory issue..

After octave start I have 

21664 K used memory as working set
a="prova.png";  
 21668 K
x=1:100; 
 21684 K
plot (x,x);
 62420 K
print( "prova1.png","-dpng");
 62432 K

every successive print command increase the memory 
foot print of 8K until it crash
sometime is only after few trials sometime I reached
12 print's before crash.

Only the print is causing such memory increase,
if I repeat the plot or the assigment the memory 
consumption stay flat.

Regards
Marco
