Extension host terminated unexpectedly (always)

[ferreteleco]

Issue Type: Bug

Update to VSCode latest release (June 2022). The extension host crashes almost instantly, displaying the infamous "Extension host terminated unexpectedly 3 times within the last 5 minutes." after retrying reload it.

In the developer tools / extension host log I cannot find any clue on what is happening.

Similar to OP (but Windows 11), reinstalling 1.68.1, and setting updates to manual has provided a workaround for my setup. Something broke in 1.69 for me.

[patrickt-oforce]

@jafin have you a link to download version 1.68.1?

[ferreteleco]

Enjoy yourself https://code.visualstudio.com/updates/v1_68

[patrickt-oforce]

@ferreteleco thank you

[patrickt-oforce]

Similar to OP (but Windows 11), reinstalling 1.68.1, and setting updates to manual has resolved my setup. Something broke in 1.69

This solve the error, for me

[MoazAlkharfan]

Yeah, 1.69 broke the extension host for me.

[psulek]

Yeah, 1.69 broke the extension host for me.

same for me.

[nafoet]

Yeah, 1.69 broke the extension host for me.

For me it's the same. The new version completely broke every extension, which do not load anymore.

Vscodium 1.69, however, does not have this problem, with identical setup.

This resolves the issue for me as well

[aldrichtr]

Not sure if it is significant or not, but my install is 'User', as opposed to 'System'

[NemesisRE]

Same Problem both on Windows and Linux

[ferreteleco]

The issue persist after upgrading to 1.69.1

[ferreteleco]

Any update on this @alexdima?

[deepak1556]

Can you follow the steps from https://github.com/microsoft/vscode/wiki/Native-Crash-Issues#creating-and-symbolicating-local-crash-reports and attach the crash report when the extension host terminates.

[nafoet]

Hi. Here are my *.dmp reports reports.zip.

[patrickt-oforce]

I have the same issue, on 1.69.1; that is the dmp reports reports.zip PS: i'm using linux

Out-of-memory when compiling a wasm target. Seems related to the mid-tier register allocator feature of V8 that got enabled in Chromium 100, https://bugs.chromium.org/p/v8/issues/detail?id=12320 and https://bugs.chromium.org/p/chromium/issues/detail?id=1287331

As next step, it would be great if users can narrow down the problematic extension using extension bisect https://code.visualstudio.com/blogs/2021/02/16/extension-bisect#_welcome-extension-bisect to help us repro the issue.

@alexdima once we know the extension, we can then try to isolate a repro with the extensions' wasm file and report an issue with V8 to investigate this further.

When this issue appears in 1.69, i've used the bisect method to find extension that cause problem; but method found no guilty extension

[Zankroh]

For me, Bisect found the faulty extension : Regex Workbench I keep this extension disabled and works great now Thanks :+1:

[patrickt-oforce]

AS @Zankroh i've rerun the extension bisect and seems the RegexWorkbench cause the extension host to fail

[nafoet]

As others have mentioned, I disabled Regex Workbench and now everything works again. Thank you.

[ferreteleco]

As mentioned, extension bisect showed Regex Workbench as the guilty extension. Uninstalling it seems to prevent Extension Host crashes.

[deepak1556]

Thanks for narrowing down the extension, I also see that users have filed issues with the extension related to this https://github.com/stephen-riley/regexworkbench/issues.

@alexdima the extension and wasm library it relies https://github.com/stephen-riley/pcre2-wasm/tree/master hasn't gotten any updates in the last 2 years and the issue seems localized to the wasm file shipped with this extension. I couldn't repro this issue with loading other wasm files (tried anycode extension), I am going to close this issue for now. Can revisit if the extension author needs help in filing an issue with V8.

Is there anything we can do on our side to prevent the crash? Should we also report this to Chromium? If this reproduces in Chromium, it would be possible to write a website which loads this particular WASM and consistently crashes Chromium.
