Bug#649431: segmentation fault in asterisk -r

[Troy Telford]

After running an apt-get dist-upgrade (which upgraded perl, among other things)

I now have discovered new behavior:

With every valid TERM=<foo>, 'asterisk -r' segfaults.  The list I tried (ie. export TERM=<foo>; asterisk -r) is:
Eterm
ansi
cons25
cons25-debian
cygwin
dumb
hurd
linux
mach
mach-bold
mach-color
pcansi
rxvt
rxvt-basic
rxvt-unicode
screen
screen-256color
screen-256color-bce
screen-bce
screen-s
screen-w
sun
vt100
vt102
vt220
vt52
wsvt25
wsvt25m
xterm
xterm-256color
xterm-color
xterm-debian
xterm-mono
xterm-r5
xterm-r6
xterm-vt220
xterm-xfree86

It appears that TERM must be set to an invalid terminal type (ie. nothing in /lib/terminfo) for 'asterisk -r' to work:
export TERM=unknown
	Connected to Asterisk 1.8.7.1~dfsg-1 currently running on voip (pid = 28745) 
	No entry for terminal type "unknown"; 
	using dumb terminal settings. 
	voip*CLI>
export TERM=something_random
	Connected to Asterisk 1.8.7.1~dfsg-1 currently running on voip (pid = 28745)
	No entry for terminal type "something_random";
	using dumb terminal settings.
	voip*CLI>
export TERM=to_infinity_and_beyond
root at voip:~# asterisk -r
	Connected to Asterisk 1.8.7.1~dfsg-1 currently running on voip (pid = 28745)
	No entry for terminal type "to_infinity_and_beyond";
	using dumb terminal settings.

If TERM doesn't exist, or is a valid terminal type, I get a segfault.
root at voip:~# unset TERM
root at voip:~# asterisk -r
	Connected to Asterisk 1.8.7.1~dfsg-1 currently running on voip (pid = 28745)
	[429565.756093] asterisk[30475]: segfault at ffffffff801512c0 ip 000000000051ed74 sp 00007fff80150980 error 4 in asterisk[400000+1a3000]
	Segmentation fault

root at voip:~# export TERM="linux"
root at voip:~# asterisk -r
	Connected to Asterisk 1.8.7.1~dfsg-1 currently running on voip (pid = 28745)
	[429601.269320] asterisk[30481]: segfault at 27772270 ip 000000000051ed74 sp 00007fff27771930 error 4 in asterisk[400000+1a3000]
	Segmentation fault

I hope this helps nail down the problem.
