    // In case the shell script QTemporaryFile object is alive during debugging:
    // 1) the sh process started in DebugSession::execInferior() exits immediately with the code 126
    //    (which means "A specified command_file could not be executed due to an [ENOEXEC]  error");
    // 2) the GDB command `source path/to/runscript` fails with the following error message:
    //    "/path/to/runscript:2: Error in sourced command file:
    //     could not connect: Connection timed out.";
    // 3) and the debug session is stuck in the starting state, so the test
    //    fails due to a timeout while waiting for the first paused state.
    // These errors likely occur because the QTemporaryFile object always keeps
    // the unique temporary file open internally (according to its documentation).
    // Prevent the errors by destroying the QTemporaryFile object before starting debugging.
