Btw, I see a similar behavior from the console, if I start GDB with
the -i=mi option, like Emacs does: when you type Ctrl-D after invoking
"pi", you can no longer interact with GDB: any input you type exits
GDB and gets interpreted by the shell instead.

So maybe this is a GDB bug that needs to be reported to the GDB
developers?
