cpptools-srv quit unexpectedly about vscode-cpptools

[sean-mcmanus]

@HazemAlindari We believe we have a fix for this in our next 1.21.0 release.

[sean-mcmanus]

@heartacker We're not sure yet. We're working on reviewing other changes we want to get in. Possibly this week. You can check the current estimated Due Date for the 1.21.0 milestone at https://github.com/microsoft/vscode-cpptools/milestone/168 .

[schack-lindemann]

After switching to the pre-release version 1.21.0 I still experience constant crashes. I can't even open VS Code without cpptools-srv crashing 2-3 times.

@schack-lindemann Okay, we'll look into it more for 1.22.0. Your call stack indicates that something is triggering the cpptools-srv.exe process to shutdown (maybe some change in configuration) and then it's crashing during the shutdown.

[heartacker]

@HazemAlindari We believe we have a fix for this in our next 1.21.0 release.

Thank you and when can we expect to get it

[sean-mcmanus]

@HazemAlindari We believe this is fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.21.0 (let us know if you're still seeing it or any other crashes).

[terrencebarr]

Hi,

What is the status on this? I am experiencing the same frequent crashes, which makes working with the extension very painful. I've also upgraded to the latest prerelease version, but no improvement.

Thanks

[sean-mcmanus]

@schack-lindemann Oh, sorry, I missed your message earlier.

We thought this got fixed at least for some cases. Is anyone on this thread seeing it fixed with 1.21.0, i.e. the people who reported it for 1.20.5?

@terrencebarr Is your crash call stack the same?

[terrencebarr]

Hi @sean-mcmanus

Thanks for the quick reply. I am using v1.21.0 (pre-release). My stack trace seems the same, but I'm attaching it just in case.

@schack-lindemann @terrencebarr We made multiple fixes that could potentially cause this issue with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.21.1, but since we weren't able to get a repro we're not sure if it's fixed or not. Can you see if it still repros with that version? Also, if it still repros, do you have any more info on when the crash occurs or if there are scenarios where it doesn't occur? It's a crash on startup and not shutdown?

[sean-mcmanus]

FYI, there's a known crash with modules_cleanup at #12479 .

Have just completely reset VScode and reinstalled all extensions. I installed the C/C++ pre-release v. 1.21.1 from the start and the problem still persist. It seem to happen more or less randomly, but always at startup and shutdown of VScode and also when opening any C based file. I mainly use VScode writing code for microcontrollers like Arduino and ESP8266 and the extension crashes when opening/closing all these files.
