[Octave-bug-tracker] [bug #45604] Windows XP Octave 4.0.0 plot crashes

[Dan Sebald]

Follow-up Comment #6, bug #45604 (project octave):

OK, then this likely is not an opengl/Qt issue.  So, I'm going to bounce the
problem with

warning: opengl_selector::select: selection buffer overflow

over to bug https://savannah.gnu.org/bugs/?45540 under the assumption that it
is a separate issue.

The crash problem might be a segmentation fault with assigning memory hunks
for the large number of curves in the plot.

You could maybe try a few things that might give some insight to what is
wrong.  For example, you could starting with a low number of curves, say


x=100
y=1:100


and increase/decrease the number to see if/when a failure occurs.

You might try looking at the properties of the plot/axes to see if there are
any clues, e.g.,


get(gca)
kids = get(gca, 'Children');
get(kids(1))


Probably won't lead to much but any clue helps.  I'm just surprised how long
even 100 curves takes to plot.
