Status: WontFix (was: Assigned)
My change is just for the component build which isn't shipped.

Comment 7 by samans@chromium.org, Mar 19 2018 

My blamed CL is reverted.

Comment 8 by g...@chromium.org, Mar 19 2018 

...And to round it out, it's unsurprising if the new AFDO profile caused this. We roll a new one every day, so the referenced profile is long gone at this point. :)
