[Scilab-users] Scilab is crashing -- on one machine only

On one machine, Scilab crashes, with a segmentation fault.

On the other, it perks along happily.

The "bad" machine had the normal Ubuntu installation of Scilab (5.5.2),
then I wiped that and installed 6.0.0 -- same thing.  I just
reinstalled the Ubuntu version -- crashes.

scilab-cli works

The "good" machine is the same Ubuntu distro (16.04, 64-bit).

Any clues as to what may be happening?

Re: Scilab is crashing -- on one machine only

Dear Tim!


This is not Scilab bug, it's bad attempt to fix CVE-2017-1000364 security bug in Linux kernel.
Debian 7, 8, 9; Ubuntu 14.04 LTS and 16.04 LTS are affected (seehttps://bugs.launchpad.net/bugs/1699772).

The temporary solution is to reboot with previous kernel versions:
* Debian 7 (wheezy): <= 3.2.78-1
* Debian 8 (jessie): <= 3.16.43-2
* Debian 9 (stretch): <= 4.9.30-2
* Ubuntu 14.04 LTS (trusty): <= 3.13.0-119
* Ubuntu 16.04 LTS (xenial): <= 4.4.0-79

Canonical and Debian will release normal kernel updates soon.

Re: Scilab is crashing -- on one machine only

Thank you very much!  I missed that thread.  It's good to know what the
issue is.

Hopefully I can just wait it out -- if not, I know how to reboot with
an older kernel.
