Can confirm this issue locally on my current system.
Running Steam through the "primusrun" Bumblebee wrapper to start games on the nVidia card leads to the following error after starting a game:
malloc: unknown:0: assertion botched
free: called with unallocated block argument
last command: (null)
Aborting...Aborted (core dumped)
I can also confirm that downgrading libdrm-intel1 to 2.4.56 fixes the issue and allows the game to run on the nVidia card just fine. Furthermore, starting Steam without "primusrun" (thereby causing the game to start on the Intel card) also does not cause this issue.
Should any testing be desired, I'd be happy to oblige.
