Summary:                    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
