gdb repl: source code is printed on an infinite loop

gdb repl: source code is printed on an infinite loop

Hello.

I got a broblem when I start gdb from Emacs.
I can start gdb (M-x gdb) on an executable I compiled with the -g flag.
But after I set a breakpoint from the gdb repl, the begining of the source code is printed at the gdb repl again, and again, and again.
Like Emacs is trapped on an infinite loop. After some seconds Emacs freeze.
I use Emacs 26.3 and I've installed Irony-mode. But no special modification on gdb integration.
Have you get the same problem or have any idea?
A search on web didn't help me.
Ho, I got the exact same problem with "emacs -q".
Could it be a bug introduced with 26.3?
Or could it be from GDB?

Please tell on what OS is that, and where did you the GDB binary you
are using in this case.

I use Fedora 31 and GDB 8.3 from the official fedora-updates
repository.
To be more precise, the installed pkg is 8.3.50.20190824.
