With the latest update to chrome, the page crashes with an 'Aww Snap' something bad happened. Chrome dev tools gets disconncted. Steps: visit https://www.chatment.com/testApp Looks like this simple script fails. π="͎ɂͥůȏ+Ů%Ǫ;Ŭɥ\u0019Ȭh͊dzɯ+ɯʌ\u0017ɩɰW̠Ț̪ŕȔ-ű`ƭ͡ģɣ\u0011ɸ/ͱǢȣ!ɩˀ%ȨȠ\u001bͯą̏𝛙𝖥𝞞𝛙𝞜𝘙𝓌𝛜𝗢𝟐Ȯj̫ƭȉ";eval(((θ,ϕ)=>((π=[..."̈́ȡ̊āɼDĂ@DŽ̒ăȂ1ȌĴƖȃGȀʬ@ȆȂ;"]['\x6d\x61\x70']((π)=>π['\x63\x6f\x64\x65\x50\x6f\x69\x6e\x74\x41\x74'](0))),(ϕ=π['\x6c\x65\x6e\x67\x74\x68']),[...θ]['\x6d\x61\x70']((ϵ,Λ)=>String['\x66\x72\x6f\x6d\x43\x6f\x64\x65\x50\x6f\x69\x6e\x74'](ϵ['\x63\x6f\x64\x65\x50\x6f\x69\x6e\x74\x41\x74'](0)^π[Λ%ϕ]))['\x6a\x6f\x69\x6e']('')))(π)) expected output is console.log, 'Hello World; This is a test file.𝟘𝟙𝟚𝟛𝟜𝟝𝟞𝟟𝟠𝟡' What is the expected behavior? Have the webpage load the javascript script correctly. I tested on a raw/uncompiled version, and that works just fine. In the meantime I will work on a simplified example. What went wrong? Got an 'Aww Snap' error instead of the page working as expected. Did this work before? N/A Chrome version: 71.0.3578.80 Channel: stable OS Version: 10.0 Flash Version:

this version of the included script works....

(which just replaces '\x63....' sort of strings with their proper words.

Broken in 71.0.3574.0 by r597569 "Update V8 to version 7.1.285" Fixed in 72.0.3585.0 by r600835 "Update V8 to version 7.2.41" The fix was probably 779d102ca87bddd412d9a9d761d6e6b57e01a609 Attaching a copy of the repro just in case.

Able to reproduce the issue on reported chrome version 71.0.3578.80 using Windows 10, Ubuntu 14.04 and Mac 10.14.1. As this seems to be fixed in latest canary 73.0.3637.0 here's reverse bisect info(....C#3) Bisect Information: ------------------- Last Bad Build: 72.0.3584.0 First Good Build: 72.0.3585.0 You are probably looking for a change made after 600834 (known good), but no later than 600835 (first known bad).

And requesting a merge to M-71, if required. Thanks!

Per comment #5, this is already fixed in M72 branch 3626, so removing M72 labels.

The fix (https://bugs.chromium.org/p/chromium/issues/detail?id=895860) should have been merged a month ago IMO. given the current release constraints around Christmas let's simply wait for 72.

Thank you hablich@. Removing "RBS" per comment #9.

That does solve the one line script. It does not solve the actual app... (as in today 71.0.3578.98 ) the script works... But the webpage still throws an aww snap.

I don't know what is different between one content in the wrapper and another... I tried a few obvious things; the only real difference is the length(?). The above script line was generated with the exact same process which takes a JS, and wraps it in that code... loading even from file:// fails, and debugger tools is crashed too.

Reporter, the underlying bug was fixed in Chrome 72, not in 71.

Thank you; I was unclear about that. There was a minor update, that when I went to try to simplify the simple example I found THAT worked... and was making sure both would be fixed. |
