Steps to introduce:
1. Install Ubuntu 14.04 LTS or Ubuntu 16.04 LTS.
2. Install Scilab 5.5.0 or 5.5.2 (sudo apt-get install scilab).
3. Install all system upgrades (sudo apt-get update; sudo apt-get upgrade)
4. Get new kernel with new updates
linux-image-3.13.0-121-generic (in Trusty) /
linux-image-4.4.0-81-generic (in Xenial).
5a. Try to start Scilab from GUI - it crashes.
5b. Try to start Scilab from terminal - it reports "Segmentation fault (core dumped)".
Expected results:
* Scilab is working normally with new kernel.
Actual results:
* Scilab is crashing with new kernel (linux-image-3.13.0-121-generic in Trusty / linux-image-4.4.0-81-generic in Xenial), but works with previous one (linux-image-3.13.0-119-generic in Trusty / linux-image-4.4.0-78-generic in Xenial).
Notes:
* First discovered and documented by ubuntu-fr (see https://forum.ubuntu-fr.org/viewtopic.php?id=2011162) and then Philippe Roux on Scilab MailingLists (http://mailinglists.scilab.org/Scilab-users-scilab-gt-Segmentation-fault-td4036624.html).
* The problem exists on both 32-bit and 64-bit architectures.
* Temporary solution is to use previous kernel.
* The problem may be related to these: new "linux-image-4.4.0-81-generic Regression: Oracle Java plugin crashes" (bug 1699772) or old "scilab libraries are heavily underlinked, causing segfaults on load" (bug 1299686).
* SegvReason is "writing unknown VMA".
* May be related to CVE-2017-1000364 (see bug 1698919).
