Description Kdwk 2023-04-29 23:31:17 PDT

1. Visit https://www.apple.com/iphone-se/
2. Keep scrolling down
3. WebProcess crashes.

I'm unable to provide coredumpctl results because the stack trace is empty (all n/a)

This crash eventually makes Gnome Web unresponsive, and the Quit dialog comes up. Tested on Gnome Web 44.2/ WebKitGTK 2.40.1

I have not managed to make the WebProcess crash as of 263795@main
There are a few animations done during the scroll that are janky,
but otherwise the crash seems gone for now. If anyone can reproduce,
it would be great to have a backtrace to be able to investigate.

@kdwkleung: Do you recall which WebKitGTK version were you using
when you hit this issue? If it was a release, it might be possible
to find the commit that fixed the issue and backport it.

I cannot reproduce this crash anymore. Closing.

Comment 4 Kdwk 2023-05-08 05:42:10 PDT

Oh no I can reproduce it again with MiniBrowser

I've seen this a few times recently too. It's effectively impossible to fix. I wonder what's going wrong such that the backtrace is so corrupted. :/
