Environment

  • OS and Version: Windows 10 Enterprise 22H2
  • VS Code Version: 1.74.1
  • C/C++ Extension Version: v1.16.3

Bug Summary and Steps to Reproduce

Bug Summary:
As soon as I open VSCode and open a cpp file I get the warning "The language server crashed. Restarting..." after some delay and after that "The language server crashed 5 times in the last 3 minutes. It will not be restarted.".
If I attach a debugger I get a "Stack overflow exception" and 5000 times "cpptools.exe!std::_Ref_count_obj2::_Destroy(void) (Unknown Source:0)" in the callstack.
I tried to reinstall the extension and VSCode completely.

Steps to reproduce:

  1. Open c cpp file in VSCode
  2. See warnings "The language server crashed. Restarting..." and " "The language server crashed 5 times in the last 3 minutes. It will not be restarted."

Expected behavior:
The extension works and does not crash

Does the language server crash if you try to down grade to the previous version 1.15.4? Does it only crash for a specific project, or does it call crash for any project such as a folder with a one simple source file?

Also as an FYI, the owner of the configuration provider vector-of-bool.cmake-tools has changed from vector-of-bool to Microsoft and is now published as ms-vscode.cmake-tools. Though the logs show that the extension does change it to ms-vscode.cmake-tools internally when it's processed.

Yes

Does it only crash for a specific project, or does it call crash for any project such as a folder with a one simple source file?
It only crashes for some projects (the newer branches of our project) for older branches or really simple projects I can not reproduce it. I will try to figure out what changed but it probably will take me some time, so if you have any hit what to look for or any other suggestion I would appreciate it.

Thanks for the hint with cmake, I updated it to the newest release version now.

This particular crash stack had been reported (outside of GitHub) and has been fixed. Using this issue to track the fix in 1.17.0.

I believe the cause is related to parsing directories containing a very large number of files, in case that might suggest any potential work-arounds.

With the pre-release it worked, I have just installed 1.17.2 and it seems the issue is fixed here as well.
