You can take your pick of the RC severities, but I don't think we should
release with a bug that makes gnuplot useless from other scripts/applications
that might call it.  Especially not if it's a regression of a bug that was
already supposedly fixed upstream.

Do you happen to have a reference to the fix or the bug report there?
I couldn't find it in the Changelog, or in their tracker so far.


I actually stumbled on this while trying to debug another issue, namely that
gnuplot silently does nothing if called from another application.
eg. if you do:

  system("gnuplot foo.script");

then gnuplot runs, and does exit, but doesn't actually appear to execute the
script ...  I'm not sure yet if these two things are related (still digging
into that), but I can definitely reproduce the original symptom of this bug,
and there's something wacky going on when it's not run from the foreground
of a shell.

Cheers,
Ron
