cpptools taking 100% cpu with kernel source when expected to be idle

[nikaiw]

Environment

• OS and Version: 6.5.0-17-generic #17-Ubuntu SMP PREEMPT_DYNAMIC Thu Jan 11 14:01:59 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
• VS Code Version: 1.86.2
• C/C++ Extension Version: 1.3.0

Bug Summary and Steps to Reproduce

Bug Summary: After opening the sources of the linux kernel and installing vscode-cpptools, cpptools started to takes 100%

Steps to reproduce:

1. git clone latest kernel source
2. open the source in vscode
3. click on a c file and install the extension
4. cpptools stuck taking 100% cpu Expected behavior: cpptools idle

attaching with gdb give the following thread backtrace I believe to be the culprit:

I didn't dig enough to know the similarity but it seems to looks a lot like past issues marked as closed: #9428 #6454 #4129 #600

Configuration and Logs

I'm running with default configuration, right after installing the extension.
