Follow-up Comment #1:

I can confirm this error in both the bar and stem functions, both of which use
a custom "baseline" property. This property references a line object, which is
where the error comes from here. When a saved figure is loaded back into
Octave, the line object that the "baseline" property refers to has not been
restored. Here is an updated example that still produces this error in Octave
5:


>> bar (1, 1);
>> s = hdl2struct (gcf ());
>> close all
>> struct2hdl (s);
>> hold on
>> bar (2, 1)
error: get: invalid handle (= -13.6531)
error: called from
