Summary:                    [patch] Segfault with limit data L(x:y) and
verbosity >= 3
Description: 
I am experiencing core dumps when I set a call time limit on for a
call. If I dont use the call time limit option then the dial
application works as expected.

For example, if I have the following dial command:

Dial(SIP/${EXTEN},,L(10800000:60000))

Then I see the following on the console when the dial is executed:

    -- Limit Data for this call:
       > timelimit      = 10800000
       > play_warning   = 60000
       > play_to_caller = yes
       > play_to_callee = no
       > warning_freq   = 0
Segmentation Fault - core dumped

If I remove the time limitation (,L(10800000:60000)) then the dial
works as expected.

If I start asterisk with the
following command:

asterisk -vvvdddgcp

then when on the console I do the following:

"core set verbose 0"
   The dial with limitation works properly

"core ser verbose 1"
   The dial with limitation works properly

"core set verbose 2"
   The dial with limitation works properly

"core set verbose 3"
   The dial with limitation crashes with a segfault

Could this be something to do with writing verbose information to the
console?

Excellent, thanks snuffy, the patch for v1.4.21.2 works correctly as well.
