page crash when debugging with DevTools

Reported by zambonif...@gmail.com, May 1 2018

Issue description

Hello everyone.

While working on an HTML canvas game, I stumbled upon a consistent crash while doing something very specific with DevTools while playing the game.

I still don’t know what specifically causes the crash, but I have tried my best to reduce my code the most while still having the crash happen.

I will attach the HTML page and JavaScript file in this issue so that you guys can reproduce it easily too.

Steps to reproduce:

1. As I’m using an ES module, launch a server that can serve both attached files.
1. Open the page named ‘crash.html’ (you should see a blank page).
2. Open DevTools with F12.
3. Reload the page (it should pause for debugging on the ‘debugger’ statement).
4. Perform “step over” in DevTools a couple times (F10).
5. The page should crash.

My system is KDE neon User Edition 20180426-1021 (based on Ubuntu 16.04).
My Chrome version is 66.0.3359.139

Able to reproduce this issue on reported version 66.0.3359.139, on latest canary 68.0.3419.0 using Windows 10, Mac 10.12.6 and Ubuntu 17.10. Tested by hosting crash.html file with simpleHTTPServer. Hence providing bisect info

Good Build: 66.0.3328.0
Bad Build: 66.0.3329.0

You are probably looking for a change made after 530866 (known good), but no later than 530867 (first known bad).

As we are unsure of the suspect for this assinging to v8 stability sheriff for this week ahaas@

@ahaas: Please help in assigning to appropriate owner. Adding RB-Stable for M-66. Please change if not the case.

Thanks!

Hi Leszek, it seems like this issue has been caused by

Can you please take a look?

Thanks for jumping on this! I see this is closed. Should the stable version be fixed now? I still see this happening on occassion ... :)
Still an issue for me, no change. If anything it may be worse
Issue 840440 has been merged into this issue.
This seems to have been fixed 👍
Not fixed for me. I did not see any available update. My snap page came up in less than a minute scannorthcounty.net/wxssgauges.php is one that is not working for me.

I can reproduce the crash mentioned in #17, but I don't think it is related to the original crash.

Georg, as the V8 stability sheriff this week, can you take a look?
I commented in #839848 that I didn't think it should be merged with this issue. I believe they are different.

Re #17, I opened a new issue at https://bugs.chromium.org/p/v8/issues/detail?id=7740. I don't think it's related to Devtools.
Issue 841159 has been merged into this issue.

Able to reproduce this issue on reported version hence verifying the fix on latest stable 66.0.3359.170 using Windows 10, Mac 10.13.3 and Ubuntu 17.10.

Now no crash is seen on using step over function. Attaching screencast for reference.

As fix is working as expected adding Verified labels.

Thanks!
