Comment # 10 on bug 86043 from 
I don't have pre 3.16 kernel easily available. 

export GAME_DEBUGGER=gdb still makes the game crash before it runs it with the
debugger.

I've tried various things to make it work (modifying the game startup shell
script) but without success. 

When I put the older version of libdrm
(86b37c61c78edd1353a3f76f678c39e2ec168771, before Tvrtkos change), gdb runs
normally for the game. So the steam binary actually crashes, not the game
itself. 

It's funny because steam binary is 32bit, Dota 2 binary is 64 bit, and only
changing the 64bit version of libdrm_intel.so affects this bug. 

I've tried debugging steam with export DEBUGGER=gdb, but it seems spawn
multiple threads and I'm not experienced with multithreaded debugging. 

I did manage to run steam with valgrind, I'll add an attachment now.
