Of course: when the program is run from GDB under Emacs, the standard output and standard input of the program are connected to a PTY (pseudo-terminal), not to a real console device. So it is a small wonder that the behavior is different. > I think it is more likely something wrong inside emacs's > gdb mode. Maybe so, but I don't see what would cause this in gdb mode.
