Comment 1

[Scoobidiver (away)]

It's more a graphics bug than a profiler one.

Do you have STR?

Comment 2

[Benoit Girard (:BenWa)]

It's caused by the profiler failing to unwind when we're running in a graphics driver in linux that dosn't have proper frame pointers. Breakpad unwinding will fix this.

Comment 3

[Kelsey Gilbert [:jgilbert]]

STR appears to be trying to use the profiler with gl-layers enabled.

Loosely speaking, the profiler is walking its way all the way into the driver, at which point it gets lost and falls down.

This appears to be fixed with `profiler.unwinder`=true, and according to BenWa:
  Alternatively if you just want pseudostack then you can turn it back off and
  turn off profiler.stackwalk and youll get simple profiles reliably.

Closing because no crash reported since 12 weeks.
