Summary:                    crash when using asterisk db put
Description: 
I have a macro that saves the sip CHANID to ast db when a call is answered
so I can save this information to the CDR.  This seems to be causing
asterisk to crash every once in a while when the CHANID variable is saved
to the ast db.  This started to happen once I upgraded from 1.4.17 to
1.4.20.1.

---------------------------------------------------------------------- 
We use MTTDial to write the sipcallid in our CDRs.  Based on gdb, asterisk
is crashing because we are using astdb to temporary store the sipcallid. 
Since this is very difficult to reproduce we decided not to write the
sipcallid to the CDRs anymore.  Here are all the macros we use to
accomplish this:

[macro-MTTDial]
exten => s,1,Dial(${ARG1}|${ARG2}|M(savesipcallid,${ARG4})${ARG3})

exten => h,1,Macro(writesavedsipcallid)

[macro-savesipcallid]
exten => s,1,Set(DB(CHANID/${CHANNEL:4})=${SIPCALLID})
exten => s,n,GotoIf(${ARG1}?HASMODE:DEFAULT)
exten => s,n(HASMODE),GotoIf($[ ${ARG1} = rfc2833]?SETRFC:DEFAULT)
exten => s,n(SETRFC),SIPDtmfMode(rfc2833)
exten => s,n(DEFAULT),Noop


[macro-writesavedsipcallid]
exten => s,1,GotoIf($[${DIALSTATUS} = CANCEL]?DONE:$[${PRIORITY}+1])
exten => s,n,Set(CDR(SIPCALLID2)=${DB(CHANID/${BRIDGEPEER:4})})
exten => s,n,Noop(${DB_DELETE(CHANID/${BRIDGEPEER:4})})
exten => s,n(DONE),Noop(${DIALSTATUS})
