Additional Information

No response

No source file or test is named. Start by reproducing the failure with the supplied Ubuntu, VS Code, C/C++ extension, GDB, and launch configuration details, then inspect the extension's step-out handling and available debugger output. Done means Step out completes successfully without the 0x80004004 error.
