> Using the CDT Debug in Container support for C/C++ applications, if a simple C application does a printf without a newline, the line may or may not be shown while stepping or running the program inside gdbserver.  It appears that the Docker daemon is not reliable in delivering output in such a case and sometimes it turns up too late (e.g. gdbserver and the application are both finished) so it does not appear.  Sometimes it shows up after gdbserver and the application is finished.  In such a case, a line containing a single LineFeed character is printed in the place it should have been printed in the first place.
