            Bug ID: 26973
           Summary: gdb crashes when not including the status window in a
                    new layout
           Product: gdb
           Version: 10.1
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tui
          Assignee: unassigned at sourceware dot org
          Reporter: ssbssa at sourceware dot org
  Target Milestone: 10.2

If you create a new TUI layout, don't include the status window, and then
change from a layout with the status window to the new one, gdb crashes.

(gdb) layout src
(gdb) tui new-layout test src 2 cmd 1
(gdb) layout test

On Windows I get a STATUS_HEAP_CORRUPTION exception (0xc0000374).
It happens because tui_apply_current_layout() deletes all windows that are =
no
longer needed, but the status (locator) window is never allocated dynamical=
ly.
