No database created during queryCompilerDefaults causing cpptools to exit

[sean-mcmanus]

I am getting this crash with the release and beta versions, and I would love to help you track this down because intellisense has always been hit or miss for me for (literally) decades!

I have attached to the 'ms-vscode.cpptools-1.22.11-win32-x64\bin\cpptools.exe' process, but it just eventually exits with exit code 0, so I can't get a stack trace from that.
Could you advise what I should attach to, and if there is a version of it with symbols?

This is the log from the Output window:

with log level=7, I got a MessageBox saying:

Command 'C/C++: Go to previous preprocessor directive in conditional group' resulted in an error
Client is not running

I didn't explicitly invoke that command, but my cat likes to walk across my keyboard!

I have 3 vscode popup errors in this order:

Sending document notification textDocument/didOpen failed

Unable to start the C/C++ language server. IntelliSense features will be disabled. Error: Error: Pending response rejected since connection got disposed
The language server crashed. Restarting...

And the log says:

I'm still using 1.21.6 (as you can see)

@adrianstephens Okay, thanks for the info -- we'll need to look into how this is possible. We haven't gotten any similar reports like this yet for 1.21.6 and that was released 3 months ago.

@sean-mcmanus Where can I take the issue of the database not being created?

I have tried pointing the database to the one generated by Visual Studio 2022 (vs\shared\v17\Browse.VC.db). I don't know if they're compatible, but I get the same pattern of behaviour (cpptools.exe eventually exits cleanly and the message about the language server crashing)
