I could not reproduce this.

Some of the odd behavior I do see seems to predate any of these changes.
With the system gdb on Fedora 28 and 29 I can:

(gdb) tui enable
(gdb) print 23
$1 = 23
(gdb) ... press Enter a a few times

Here the subsequent prompts aren't seen and the output just looks like

$2 = 23
$3 = 23
...

With git master this is worse and the output looks like:

(gdb) print 23
$1 = 23
(gdb) 
(gdb) $2 = 23

(gdb) $3 = 23

(gdb) $4 = 23


This I tracked down to the "nonl" patch.
I haven't yet debugged that one seriously.

I will look into the crash, but note that the "list" command is pretty
broken in the TUI.

So it isn't super surprising to me that it doesn't work correctly in all
cases.
