Unable to find the exact suspect from the Regression range.

Assigning to noel@ for help in investigating this further.

I authored no change in the given range.  I suppose you are just to look for help to resolve.  I scanned the regression range change logs, didn't see anything obvious.

sigbjornf@, sorry to pass this on.  Could you please have a quick scan of the regression range and see if there is anything obvious / suspect?

No clear match seen either for this crash on creation of a compositor thread. I suspect the stack is the fallout from the actual problem, but what.. Have you discounted the skia commits as being the potential source?

No, but if you suspect it's Skia, then assign to skia person :)
