Bug Summary and Steps to Reproduce

Bug Summary:

Upon stopping any debugging session, even when using just the default launch configuration, the VS Code extension host outputs the following:

There are no issues during the debugging session itself. This message only occurs when using a cppdbg type launch configuration, and not with other debug adapters (I tried with CodeLLDB).

Additional Information

No response

Reproduce the issue with the shown cppdbg launch configuration on Ubuntu 22.04, then trace the debug adapter shutdown path used when the session stops. Compare this behavior with CodeLLDB and verify that stopping a cppdbg session no longer emits the “Invalid debug adapter” error.
