Bug type: Language Service

I'm edition something on LInux that require the "lib1" headers, it keeps asking to add "/same_path_has_MYPROJECT_INSTALL_PATH/include/lib1" to the include path, over and over, even when "${env:MYPROJECT_INSTALL_PATH}include/lib1" it's already there and points to the same path.
This happens on random files and with random libs on this project. But when i compile the errors go away and sometimes they come back later.

This issue was wrongly reported on the VSCode issues (https://github.com/microsoft/vscode/issues/144830).
I think every information is there and I will add here what's missing.

  • OS and Version: Linux x64 5.16.13-arch1-1
  • VS Code Version: 1.65.1
  • C/C++ Extension Version: 1.8.4
  • Other extensions you installed (and if the issue persists after disabling them): C/C++ Extension pack
  • If using SSH remote, specify OS of remote machine: N/A
  • VSCode sometimes randomly complains about missing paths that are on include path already and even with u add using the "quick fix" the issue doesn't go away

Steps to reproduce

  1. Have a project with some headers that need a path on the include path
  2. VSCode sometimes randomly complains about missing paths

Expected behavior

Intellsense should work and find the headers in the include path

Code sample and logs

I don't know if this output are related to this specific issue.

C/C++ output:

IntelliSense process crash detected.

cpptools output:

Erste Schritte

  1. Lies das ganze Issue und danach den Beitragsleitfaden des Projekts.
  2. Schreib ins Issue, dass du es übernimmst — das erspart doppelte Arbeit.
  3. Forke das Repository und arbeite in einem Branch.
  4. Öffne einen Pull Request, der die Issue-Nummer nennt.

Rechercherichtung

Beginne mit der bereitgestellten c_cpp_properties.json und der Ausgabe von C/C++: Log Diagnostics und reproduziere anschließend die Meldungen zu fehlenden Headern sowie den Absturz des IntelliSense-Prozesses unter Linux. Erledigt ist die Aufgabe, wenn bereits im Include-Pfad vorhandene Header konsistent aufgelöst werden und IntelliSense nicht mehr abstürzt oder die Konfiguration verliert.
