Summary:                    Asterisk crash when I park a call
Description: 
Using Asterisk 1.4.18, when I try to park a call, I immediatly got a core
dump just after playback the parking lot.

CentOS 4.6, i386, kernel 2.6.9-67.0.1 (CentOS).

I thought it was pretty clear

When we transfer the call to the Park() application using *1 (BLINDXFER),
asterisk crash at each attempts.

If we do a SIP transfer or *2 (ATXFER), all work as expected and no
crash.

sip transfer = ok
blindxfer *1 = crash
attended transfer *2 = ok

Generates segfault

jvandal changes dialplan (workaround) so there is no segfault

On /etc/asterisk/features.conf, I have change

parkext=700 to parkext=disabled

and on extensions.conf, I have add:

exten => 700,1,Park()
