Sorry for the late reply. And missing information.

It is version 4.2.1 windows downloaded from here: https://ftp.gnu.org/gnu/octave/windows/
Having ghostscript: GPL Ghostscript 9.16 (taken from the error notice).

grahpics_toolkit: qt
available_graphics_toolkits: [fltk gnuplot qt]

The problem occurs with either qt and gnuplot or fltk. Where fltk also makes octave-gui crash.

I have found that the problem is related to the enormous amount of files ghostscript leaves behind in the temporary folder: C:
\Users\marc\AppData\Local\Temp/. If I remove those files, the problem tends to go away for a short amount of time (until the files build up again).

I already tested if it tries to create an already existing temporary file (and failing to do that) but that seems not to be case (at least not between script-runs).

What is further puzzling is that (for the attached script) it creates temporary files called gs_axxxxx to gs_gxxxxx (or something other early alphabet letter) when printing a figure for which nothing goes wrong. But when it fails it is always a gs_zxxxxx file.

For the attached script, as explained I for an empty Temporary folder you might need to run it some three to four times, then it will start failing every 1 out of 3 runs at leas for 1 image.

Please let me know if you need more information.

Thank you for your report. To be able to reproduce your problem, please be specific about the Octave version you are using (do you use the Windows version from https://ftp.gnu.org/gnu/octave/windows/ ?) and you might provide a small test script to reproduce the problem. Your screenshot unfortunately is not very helpful. Do you have other installations of Ghostscript (gs.exe) on your machine?

What is the output of the commands

before you start plotting? And does it help if you switched your graphics toolkit https://www.gnu.org/software/octave/doc/interpreter/Graphics-Toolkits.html ?

I create scripts that plot and print data automatically.
Every 5 to 10 graphs it plots and prints ghostscripts stops working with the windows notice "gs.exe has stopped working".
