Segmentation fault when run with optirun

[Adrian Dinu]

I have a laptop with an i5 7200U and an Nvidia 940mx. I have set up bumblebee and nvidia-390 drivers and tested things out.
When I run 'glmark2' on the iGPU everything works fine and the horse animation pops up. When I run 'optirun glmark2' I get the following output:

$ optirun glmark2
** GLX does not support GLX_EXT_swap_control or GLX_MESA_swap_control!
** Failed to set swap interval. Results may be bounded above by refresh rate.

This should be fine, this is the output that you would expect but no animation pops up and no more output is generated.

I don't think this is a bumblebee issue as running other programs with optirun, like glxgears or glxheads, works fine.
