[Octave-bug-tracker] [bug #57245] "clear all" generates segfault if run before or after a plot

[Carlo de Falco]

Follow-up Comment #30, bug #57245 (project octave):

Something rather surprising that I found out while testing
for bug #56908

if I build with fltk enabled (by adding the "--without-qt" but omitting the
"--without-fltk" option for configure)

the segfault when plotting with gnuplot does not occur, i.e.


>> available_graphics_toolkits 
ans =
{
  [1,1] = fltk
  [1,2] = gnuplot
}
>> graphics_toolkit gnuplot
>> clear all
>> plot (randn (5))
>> clear all
>> plot (randn (5))

 
produces no segfault
