[Octave-bug-tracker] [bug #50686] gs.exe stopped working

[Marc Dirix]

Follow-up Comment #2, bug #50686 (project octave):

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.
