            Bug ID: 28437
           Summary: `fs status` followed by `fs next` fails to switch
                    focus on Mac
           Product: gdb
           Version: 10.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: tui
          Assignee: unassigned at sourceware dot org
          Reporter: sourceware at fastmail dot com
  Target Milestone: ---

GDB 10.2 installed from macports, NOT 10.1 (but I don't see it in the list)

Switching focus in tui mode breaks.
To repro:

```
$ gdb -tui ./baseq3/cpma/bin/a.out
Reading symbols from ./baseq3/cpma/bin/a.out...
Reading symbols from
/Applications/ioquake3/baseq3/cpma/bin/a.out.dSYM/Contents/Resources/DWARF/a.out...
(gdb) fs status
Focus set to status window.
(gdb) fs next
/opt/local/var/macports/build/_private_tmp_macports-ports_devel_gdb/gdb/work/gdb-10.2/gdb/tui/tui-data.c:116:
internal-error: struct tui_win_info *tui_next_win(struct tui_win_
info *): Assertion `cur_win->can_focus ()' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

(ABRT)]

```
This works with whatever code is being debugged, I repro with a hello world in
C
