gdb tui support broken ("layout regs" gives internal error, "layout split" gives core dump

[James Hunt]

Binary package hint: gdb

The tui "layout" commands appear rather "fragile":

________________________________________________

1) "layout regs" causes a gdb internal error

To recreate:

gcc -g file.c
gdb --tui a.out
(gdb) b main
(gdb) layout regs
(gdb) r
Starting program: /home/james/src/c/a.out
/build/buildd/gdb-7.2/gdb/i386-linux-nat.c:562: internal-error: Got request for bad register number 41.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
________________________________________________

2) "layout split" causes gdb core dump

To recreate:

gcc -g file.c
gdb --tui a.out
(gdb) b main
(gdb) layout split
(gdb) r
Segmentation fault (core dumped)

Notes:

- problem occurs with and without ~/.gdbinit
- problem appears independent of terminal size (occurs with 24x80 and 48x143).

closing this rather old issue. sorry for not addressing this earlier. Please could you recheck with the recent 14.04 LTS or 14.10 releases and reopen the issue if the problem persists?
