[Octave-bug-tracker] [bug #50189] Segfault when drawing sphere as first plot

[Markus Mützel]

Follow-up Comment #24, bug #50189 (project octave):

For what its worth, the results from the tests from comment #15 and comment
#16 in Matlab R2016a:

>> labels = {'xlabel', 'ylabel', 'zlabel', 'title'};
hlabels = cell2mat (get (gca, labels));
Error using cell2mat (line 52)
CELL2MAT does not support cell arrays containing cell arrays or objects.


Fails because graphics handles are objects now.
Slightly modified keeping the spirit of the test:

>> close all
>> labels = {'xlabel', 'ylabel', 'zlabel', 'title'};
>> hlabels = get (gca, labels);
>> hparents = get ([hlabels{:}], 'parent');
>> all ([hparents{:}] == gca)

ans =

     1

>> allchild (gca)

ans = 

  0x0 empty GraphicsPlaceholder array.
