gdb/gdbserver behavior changed from 8.2 to 8.3

Sometimes I have to debug GUI or curses based programs. Up to the change from gdb 8.2 to 8.3, I used to do: 1) from one console: gdbserver port:1111 path_to_exe 2) from another console: gdb -ex "target remote localhost:1111" path_to_exe And I was happy... Now with gdb 8.3, when I run 1), I get the following error: port:1111: cannot resolve name: Name or service not known Exiting Does anybody knows what I have to do to solve this issue? Thanks, Xavier
