--- Comment #25 from Eero Tamminen <eero.t.tamminen at intel.com> ---
With latest Mesa, DOTA2 is crashing also for me on HSW (GT3e) after starting
DOTA2 Tutorial.

Toggling overlay off doesn't help, nor does changing graphics options from
maximum to minimum.

While this could be related to bug 82759, DOTA2 works for Tapani with latest
Mesa so I think it unlikely.  With  Mesa v10.1 in Ubuntu 14.04, DOTA2 works
fine (both from Steam & and command line), so my DOTA2 install itself is in
working condition.

Gdb doesn't show anything useful.  Program counter points to zeroed memory
(clearly invalid for code), and addresses in backtrace aren't addressible i.e.
program seems to have jumped to invalid/wrong address and either that had
corrupted the stack (as return address there is invalid), or stack corruption
caused jump to wrong place.

DOTA2 takes too much memory that I could run any of the memory debuggers
(valgrind, duma).
