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?

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

Status in “gdb” package in Ubuntu:
  Invalid

Bug description:
  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)
