[Octave-bug-tracker] [bug #61994] Crash on GUI exiting with octave_base_value objects still open.

[John W. Eaton]

Follow-up Comment #33, bug #61994 (project octave):

It definitely could be due to changeset
http://hg.savannah.gnu.org/hgweb/octave/rev/fc530ec01070, however I'm unable
to duplicate the problem with


DISPLAY= /bin/bash run-octave -disable-asan --norc --silent --no-history
--path /home/jwe/src/octave/doc/interpreter --eval "genpropdoc ('figure');" >
doc/interpreter/plot-figureproperties.texi-t


on the same buildbot system where the failure is happening for the buildbot
build, or by running the command in the actual same directory where the
buildbot failure occurs while logged in as the buildbot user and running
without DISPLAY set.  I see the gnuplot warning but not the crash.

For now, I can undo the change.

The failure happens when generating the distribution tar file for the current
sources and I see that it doesn't use 'xvfb' for that build step.  We could
also change that, but then a problem like this would have been unnoticed.

While looking at this problem I also noticed the following message in the
http://buildbot.octave.org:8010/#/builders/33/builds/1266/steps/6/logs/stdio
log file:


sh: 1: dvipng: not found
warning: latex_renderer: a run-time test failed and the 'latex' interpreter
has been disabled.
warning: called from
    text at line 218 column 10
    plotimages at line 107 column 7


I can install dvipng on the build system to avoid the warning.  I wouldn't
make it a high priority, but I'm also wondering whether there is some easy
change we can make so that we don't miss things like this in the buildbot log
files.
