This is probably the long standing steam runtime compatibility issue with mesa 10.5 and newer. You can either try the arch workaround or disable the steam runtime with USE="-steamruntime". NOTE: Disabling the steam runtime makes it your responsibility to manage library dependencies and dependency issues should be reported to the package maintainer.
=x11-drivers/nvidia-drivers-361.28 ships a known defective version of libglvnd, either use a different version or update to x11-drivers/nvidia-drivers-361.28-r2 and use the compat use flag, which removes libglvnd from the render path.
Another potential snafu is the virtualgl bridge that is used by default with optirun, which is known to misbehave with some applications and in general suffers a greater performance penalty than the primus bridge.
@Tele42, thanks for reply. I have mesa-11.0.6 installed.
The arch workarounds didn't work, unfortunately.
update to x11-drivers/nvidia-drivers-362.28-r2
You probably meant x11-drivers/nvidia-drivers-361.28-r2. Upgraded to this version.
Primus, unfortunately, has never worked well for me. Actually, it simply didn't work most of the time. But this time it works! Even primusrun steam works. primusrun glxinfo | grep render outputs OpenGL renderer string: GeForce 940M/PCIe/SSE2. Although, primusrun glxgears shows only 50 fps (the Intel card performs 16 times better. Well, the steam client is running on nVidia card, at least. That's something.
The only thing I didn't try is USE="-steamruntime". I doubt it's worth it. But I'll try.
Still, is it a mesa bug, or something else? The strange thing is that primusrun steam successfully launches the steam client, while "steamruntime" and mesa-11.0.6 are still on their places. I mean I'm not sure whether this ticket should be closed, or not.
Thanks.
@rosmanov sorry about the typo, I corrected it to 361.28-r2 above.
Since primusrun works, then the issue most likely is coming from the virtualgl bridge in optirun. 50 fps sounds like a forced vsync issue and as long as it's steady and smooth, you probably actually want it in place to help manage the laptop's temperature. You could also give optirun -b primus a try, but I don't know if it'll behave any different from primusrun.
The issue is somewhat fixed for me, - the steam client works on primus. Performance seems not as good as it used to be a couple of months ago, however.
I've also tried to disable "steamruntime". After installing some packages I've managed to launch it successfully. Some games require extra packages.
So I'll leave the ticket status to your discretion. Maybe there is something to fix on the steam side.
Although it somehow works with primus, performance is pretty bad. I tried to launch steam on another laptop where I know exactly how it performed before the crashes. Now even primus fails to launch it.

After the crash, all attempts to launch it with or without LC_ALL=C failed.

It's an Asus laptop with integrated Intel video card and discrete(Optimus) nVidia video card. Both cards are capable of running OpenGL applications. However, the steam client fails to run on nVidia card through
bumblebee.Steps for reproducing this issue:
optirun steamcommand in terminal.The steam client crashed with segmentation fault. Reproduced at 100%.
Note, the steam client has been crashing after an upgrade about 1-2 months ago. The upgrade included everything, including the steam client (which is upgrading itself automatically on startup). So I don't know exactly which software upgrade caused this issue.
