Vedran thanks for bisecting this :-) I'm not sure how this patch can cause such an issue. Either something funny has happened during bisect or there is another underlying problem.
Summary of the problem so far:
Optimus system running Intel mesa and the proprietary Nvidia drivers. Running Steam (games) with either bumblebee, optirun or primusrun seems to cause a crash.
Steam Log: Game update: AppID 550 "Left 4 Dead 2", ProcID 9399, IP 0.0.0.0:0 ... malloc: unknown:0: assertion botched free: called with unallocated block argument last command: (null) Aborting...Game removed: AppID 550 "Left 4 Dead 2", ProcID 9399
Bisecting libdrm shows ae8edc7544e as the offending commit.
If an Intel dev has a similar machine they can try to reproduce it locally. Otherwise a back-trace should help at least a bit.
I while back I was able to use gdb with steam. Not sure if it still works * Close all steam games and the steam client * $ export GAME_DEBUGGER=gdb * $ steam
Note I'm not looking into the issue, just trying to get some information for the Intel devs.
