I think this is expected: the MI interpreter used by Emacs causes
different outputs to be emitted by GDB than when you use the
equivalent CLI interpreter commands.

The information you see when you type GDB CLI commands into the gud
buffer is shown in the "many windows" when you use the GUI controls.
So no information is lost.

Can you tell why the current behavior is a problem?
