[Jordi Gutiérrez Hermoso]

Update of bug #33618 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #3:

I don't think we can support this easily soon, since it seems to depend on the
underlying support that imagemagick can give us, but more distressing, these
commands segfault my build at cset :


image = rand(5,5,5,5)
imwrite(image,'image.gif','gif','DelayTime',0.1,'LoopCount',2);


Whether we support it or not, we certainly shouldn't be segfaulting.

Here is the top of my stack trace:
