Summary:                    [regression] asterisk sip becomes unresponsive,
astobj2.c:115 INTERNAL_OBJ: bad magic number 0x0 for 0x9f0a828
Description: 
during dialplan configuration I observed a severe problem:

normal SIP account:

[steinwendtner]
type=friend
md5secret=efe7d3d521f817dsfghdfghdfh319d53da
context=sip_test_context
callerid=01229919640
callingpres=allowed
host=dynamic
mailbox=01229919640 at customer
dtmfmode=inband
canreinvite=no
nat=yes
progressinband=no
language=de
qualify=no
disallow=all
t38pt_udptl=yes,redundancy,maxdatagram=400
allow=alaw

simple dialplan:

[sip_test_context]
exten => 640,1,Hangup


sip ATA dials 640, call gets disconnected as expected (603 declined)
After this, it becomes unresponsive. SIP ATA cannot register anymore.
Sometimes I get tons of:

[May 12 07:55:17] ERROR[29092]: astobj2.c:115 INTERNAL_OBJ: bad magic
number 0x0 for 0x9f0a828
[May 12 07:55:17] ERROR[29092]: astobj2.c:115 INTERNAL_OBJ: bad magic
number 0x0 for 0x9f0a828

sometimes asterisk crashes

---------------------------------------------------------------------- 
Users have been sufficiently warned about the impending suspension of
support for the 1.6.0 and 1.6.1 series for at least 2 month now heavily
(and originally announced on http://www.asterisk.org/asterisk-versions in
December of 2009).

Not all issues could possible be resolved in the 1.6.0 and 1.6.1 branches
prior to the end of support, which is why people should switch to 1.6.2 if
they require continued maintenance support.

For those who directly run into this issue can utilize Asterisk 1.6.2.x.
Those who do not have issues with 1.6.0.28 or 1.6.1.20 can continue using
those versions for as long as they wish.
