Follow-up Comment #6, bug #34631 (project octave):
I have explored this a bit more and could identify different symptoms from
which I can learn that there are at least two type of problems !
Symptom 1 - font related errors
The font related errors are for sure common for both gnuplot and fltk. This
can be reproduced with 3.4.3 with both backends by opening a single figure and
generating multiple text objects:
figure;
plot(1:10);
max_texts=504;
for ti=1:max_texts
ti
text(rand(1,1)*10,rand(1,1)*10,sprintf('test_%03u',ti));
end
I could reproduce it on two different machines, an win7-x64 and an xp sp3.
On both machines it fails: with fltk on text object 504 and with gnuplot on
text object 503.
With 3.2.4 - it doen't happen with gnuplot but with high number of texts
graphics response became very slow.
Symptom 2 - multitude figures problems
max_figures=86;
for ii=1:max_figures,
ii
figure;
plot(1:10);
end
gnuplot:
On WIN7-X64/3.4.3/gnuplot and XP-SP3/3.4.3/gnuplot, I could reproduce it with
max_figures>=86
On Win7-X64/3.2.4/gnuplot and XP-SP3/3.4.3/gnuplot, I could reproduce it with
max_figures>=256
The error I am getting is:
> error: fputs: invalid stream number = -1
fltk:
On WIN7-X64/3.4.3/fltk I can't since the font related issues appears earlier
at figure 102
On WIN7-X64/3.2.4/fltk I can plot many figures but some remain blank.
On the XP-SP3/3.4.3/fltk and XP-SP3/3.2.4/fltk the problems are much more
severe:
Octave crashes (disappears) inconsistently between figure 11 to 35. It seems
that pause commands between the figure and plot commands tend to get more
figures before crashing but I am not sure.
I didn't have a chance to repeat these tests on another XP machine (to
eliminate the chance that this XP machine may have a problem with its graphics
driver).
I beleive that the font related issues will be easy to be tracked.
The multitude figures issues are not so severe except for the XP/fltk !
(Please repeat the XP/fltk to eliminate the chance that my machine has another
problem with system or graphics)
