[Octave-bug-tracker] [bug #52998] Segmentation fault for OpenGL printing of non-visible figures

[Sahil Yadav]

Follow-up Comment #1, bug #52998 (project octave):

I have also noticed a problem related to print lately:

When printing something to a printer, if the printer doesn't exist, octave
exits with SIGABRT (signal 6).

The output for version 4.0.0 is (which works fine in handling the exception):


>> clf()
>> surf(peaks)
>> print -dpswrite -PPS_printer
lpr: PS_printer: unknown printer
warning: broken pipe

>>


While the output for version 4.2.1 (stable) is : 


octave:1> clf()
octave:2> surf(peaks)
octave:3> print -dpswrite -PPS_printer
lpr: PS_printer: unknown printer
warning: broken pipe
error: gl2ps_renderer::draw: internal pipe error
terminate called after throwing an instance of 'octave::execution_exception'
panic: Aborted -- stopping myself...


Whereas, the following was the output for the dev branch:


octave:1> clf()
octave:2> surf(peaks)
octave:3> print -dpswrite -PPS_printer
lpr: PS_printer: unknown printer
  ./base/gsicc_manage.c:1088: gsicc_open_search(): Could not find

I could've posted it as a new bug but thought of it as almost the same problem
that you encoutered and so posted it here as a comment.
