Closed cetygamer closed 2 years ago

cetygamer commented 2 years ago

Bug type: Language Service

Describe the bug

Steps to reproduce

  1. Open cpp file in the editor.

Actual behavior

IntelliSense process crash detected.

After viewing cpp file for about 2 minutes, I end up with 100 core.* files in my workspace.

Expected behavior

IntelliSense processes file without crashing.

Code sample and logs

It is quite difficult to pinpoint exact code fragment which causes the crash.

If you set "C_Cpp.intelliSenseCacheSize": 0 does that workaround/fix the issue?

Do you know if this repros with 1.7.1 (C_Cpp.updateChannel set to "Default' and extensions.autoUpdate set to false)?

It sounds like you're not able to provide a repro code sample?

cetygamer commented 2 years ago

Yes, I reproduced it with 1.7.1 first and only then switched to 1.8.0-insiders2 hoping it is fixed there.

I actually worked around it by removing "${workspaceFolder}/**" from includePath, making it empty array. After that I only see occasional crashes (maybe 1 crash right as I start VS Code and then it works fine for the rest of the session).

github-actions[bot] commented 2 years ago

Hey @sean-mcmanus, this issue might need further attention.

@cetygamer, you can help us out by closing this issue if the problem no longer exists, or adding more information.

cetygamer commented 2 years ago

Between then and now I changed a bunch of settings: removed includePath from c_cpp_properties.json, increased the size of cache, move cache to a different location. It is not as consistent as before, I'll keep an eye out and reopen if I find anything concrete.
