segfault with primusrun (not with optirun)

I have a multilayered issue here (I think). This thread is only about the titled behaviour.

When I run `optirun glxspheres64`, it runs fine (here's the dmesg)

When I run `primusrun glxspheres64` or `optirun -b glxspheres64` this is what happens:-

As is probably evident, I'm using bumblebee and bbswitch (card is an Nvidia MX150 on my laptop). Only just ran into this, and I don't remember when this last worked. Definitely did in November when I first got the laptop, but since then I haven't really had any reason to use the graphics card and it's been just kept off all the time.

When running primusrun, an error in terminal says

primusrun terminated by signal SIGSEGV (Address boundary error)

Any ideas for further investigation?

Re: segfault with primusrun (not with optirun)

And... this doesn't happen on my older laptop. Hardware is quite different, the problematic daily-use laptop is using an MX150 while the older working laptop is using a GT635M.
