Simplified repro doesn't require any files: 1. open devtools on any page and run the following: dir(alert) 2. click the output to expand it: ▶ f alert() 3. click "..." after "arguments" or "caller" Expected: "null" or nothing shown Observed: "[Exception: TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them at Function.invokeGetter (<anonymous>:2:14)]" ======================================================= Bisected to r508871 "V8" https://chromium.googlesource.com/v8/v8/+log/094a7c93..b7d76640?pretty=fuller&n=200 No idea what to suspect in this changelog.
