Linux build crashes with "Could not attach to process" on Ubuntu 15.10

Linux build crashes with "Could not attach to process" on Ubuntu 15.10 (kernel 4.1.2 or 4.2), when the build is done with unity 5.2.x or 5.3 beta.
The same build runs fine when done with Unity 4.6.9.

(fglrx amd proprietary drivers.)

I have made the builds on a win machine.

Already made a bug report case 739448.

 

This is the forum for the experimental build of the Unity editor on Linux - the correct approach was the one you took, filing a bug report.
FWIW, it looks like it's crashing deep in the driver, when Unity is setting the vsync interval - I'd check if there's an upgrade for the driver.

 

Thank you. I just couldn't find another place to post about it and wanted to know if other linux users face this issue.
I have upgraded to the latest fglrx driver that came out a few days ago and the issue persists.

 

I updated Ubuntu 15.10 to the latest kernel 4.2.0-19 and compiled an empty scene with vsync disabled.

The crash and the error log remain the same.

 

The issue persists when building for Linux on Windows7 with Unity5.3.0f2.

It is not happening when building with Unity5.2.2 Linux editor.

 

While I had still the same issue on Unity 5.3 I sat down and produced many builds with various quality settings.

I narrowed it down. It is the Antialiasing that causes the crash.

If you disable it it will not crash.
