I jotted down a few fatal errors I got in the past week that crashed my browser. I don't have a crash reporting set up. Here are the three I got:

Code: Select all

[0916/021907.816:FATAL:V0CustomElementConstructorBuilder.cpp(63)] Check failed: script_state_->GetContext() == script_state_->GetIsolate()->GetCurrentContext().

Code: Select all

[0916/021915.972:FATAL:render_frame_host_impl.cc(2578)] Check failed: GetSuddenTerminationDisablerState(disabler_type) != present (1 vs. 1)

Code: Select all

[0916/054550.496:FATAL:ScrollAnimator.cpp(165)] Check failed: run_state_ == RunState::kRunningOnMainThread || run_state_ == RunState::kRunningOnCompositor || run_state_ == RunState::kRunningOnCompositorButNeedsUpdate || run_state_ == RunState::kRunningOnCompositorButNeedsTakeover.

Not sure if they'll have any value because I don't have the information to replicate or any details. Feel free to ignore. If/when I setup crash reporting, I'll report these with more details.

I have some more now. Some I can even regularly replicate, yay!

Simply visiting https://developer.mozilla.org/en-US/docs/Web/API gives:

Visit https://www.webrtc-experiment.com/Plugi ... 5243142322 and page down real fast after comments start loading, get:

Visit https://herbertograca.com/2017/09/21/on ... hitecture/ (or if you have visited it before, force refresh sans cache), get:

Code: Select all

[0921/101658.756:FATAL:DocumentMarkerController.cpp(449)] Check failed: !document_->NeedsLayoutTreeUpdate().

Anyone want to give a try with cef simple and see whether it's just my browser or not? I figure even if it is my browser, these fatals should never occur under any circumstance.

(All of these bugs here and the previous post are on Windows btw)

Most of these look like debug assertions in Blink. You can find/file bugs at https://crbug.com.

Are you experiencing browser crashes also in release mode?

Ah, yes, I have not run my stuff extensively in release mode so I do not know. I doubt it though of course if these checks aren't compiled in. I will report back if I see any release-mode fatals.
