Hello!

OS: Kubuntu 14.04
Bash version: 4.3.11(1)-release (i686-pc-linux-gnu)

How to reproduce a bug:

(1)
address@hidden:~$ exec man !!!!!!!!!!!

(2) Then, on man execution, press q

(3) On this stage, if bash didn't exited and there is a line on the screen:

--Man-- next: man(1) [ view (return) | skip (Ctrl-D) | quit (Ctrl-C) ]

press Ctrl-C

(4) if bash didn't crash, repeat steps (1)-(4), while looking, what
happening to .bash_history file. After 2-3 times bash should crash on
step (3)

Regards, Michael
