Thanks, Rik,

I can confirm that my locally compiled 3.4.2 is fine.

This has been fixed after the version 3.4.0 that you are using.  The fix is in the 3.4.2 release available on the website but you will need to build from source.

The original bug report for this is https://savannah.gnu.org/bugs/?func=detailitem&item_id=32528

See also this duplicate which was specifically for plot on 32-bit systems https://savannah.gnu.org/bugs/?func=detailitem&item_id=33072

Thanks,

I think I changing the toolkit (presuming that the following is correct)
graphics_toolkit('fltk')
graphics_toolkit('gnuplot')

And that didn't change the error message.

Have also tried:
octave -f       # runs without loading .octaverc files
pkg unload all  # remove any packages
x = 0.1:0.1:1;
y = 0.043 * x.^0.36;
plot(x,y);

I asked about this on the Fedora forum: http://forums.fedoraforum.org/showthread.php?p=1501566&posted=1#post1501566
and got a reply that it worked with the 64-bit Fedora 15 installation (I'm running 32 bit).

I can add that the graph does appear, but the error message throws me out of whatever function is running.

Which plotting toolkit are you using?  gnuplot or fltk?  And does switching to the other toolkit solve the problem?

help graphics_toolkit

Also, for the simple example you posted, can you run it without any user customization and without any installed packages?  I want to be sure it's not something in your environment.

octave -f       # runs without loading .octaverc files
pkg unload all  # remove any packages
x = 0.1:0.1:1;
y = 0.043 * x.^0.36;
plot(x,y);

Plotting certain data gives me an out of memory error. It depends on the range and the details of the data, i.e. only crashes for particular numbers. 

Using Fedora 15 distribution.

See example below.
