I believe this issue is related to your graphic card drivers.
Are you using a virtual machine?
What operating system are you using?

[smooker]

Nope.
Real machine.
Other OpenGL programs are OK.

[Albert]

This issue seems to be related to OpenGL drivers...

Can you reproduce the crash with the latest RoboDK version for Linux?

[smooker]

More recent than this ?

SOLVED

Pardon me. Permissions on /dev/dri was wrong, causing the segfault instead of error message.

[smooker]

More clear solution for running as another user :

Code:

Section "ServerFlags"
Option "AllowIndirectGLX" "on"
Option "IndirectGLX" "on"
EndSection

in the nvidia section

Code:

Option "AllowIndirectGLXProtocol" "on"
