Suspected CLs	Findit failed to find any stack trace. Is it in a new format?

From the regression range from the CF report assigning to the original author @bruthig for https://codereview.chromium.org/2191363002 and cc'ing jamescook@ listed as reviewer.
ajha@, can you grant me permissions to the test and test results?

ajha@, How can I determine if this issue is still relevant?  Would cluster-fuzz runs continue to post to this issue as failures continue to happen?  From what I can tell this may have been fixed by chance and I don't want to waste time investigating if that is the case.
