Update of bug #54609 (project octave):
Status: None => Need Info
Follow-up Comment #1:
This is not really an error, but your grsecurity kernel killing Octave when it
is attempting to use OpenGL.
I don't use grsecurity, but some quick searching shows that pretty much any
JIT must be allowed to use mprotect. And many of the modern mesa OpenGL
drivers use LLVM JIT. So that is my guess as to what is going on here.
Please look at these forum discussions for example
Do those discussions help? I don't know anything about 'paxctl' or disabling
mprotect, but those seem very relevant to your configuration.
Or you can avoid using OpenGL, does using gnuplot for plotting help resolve
this for you?
