Ubuntu 14.04 - Segmentation fault in examples

[n-s-kiselev]

I use release 2.37 (and 2.36) on Ubuntu 14.04 (on two different mashines result is identical). Compilation went normally (only few warnings), but when I try to run examples I got: Segmentation fault (core dumped) In MacOS the same release gives no error and all examples work properly. What could be a reason for this issue? Thank you in advance!

You might have more luck with the current master branch from github. I have 16.04 here I can test with, what is your GPU/driver?

The driver for GPU is NVIDIA binary driver - version 384.130. Master branch gives the same result. Yesterday, I have check it on Ubuntu 18.04 everything works fine. Mystery! Any way thank you for your reply! Is project still alive or have you closed it?

Can you try to get a stack dump?

For example: gdb --args ./example1

Then, a where to see the call stack?

I just merged to master a fix for some compilation warnings I see for gcc 5.5.0 on Xenial.

I have checked it! Those warnings which were before indeed dissipated, but some small warnings left. I suppose it, ok. But examples still do not work, see below:

I checked just now with Ubuntu 18.04 (Bionic), seems fine.

Is there anyone using Ubuntu 14.04 (Trusty) that can confirm this problem?

valgrind seems clean for Ubuntu 18.04.
