Description:Asterisk crashes If you call the following dialplan exten:
{noformat}
exten = 100,1,NoOp()
same = n,Set(ATTENDEDTRANSFER=)
;same = n,Set(BLINDTRANSFER=)
same = n,Park()
same = n,Hangup()
{noformat}

Backtrace
{noformat}
#1  0x012044e0 in setup_park_common_datastore (parkee=0xb738d6b4, parker_uuid=0xb738d758 "1436906324.126",
   comeback_override=0xb7322568 "park-ringback,101,1", randomize=0, time_limit=90, silence_announce=0)
   at parking/parking_applications.c:353
353 parker_dial_string = ast_strdupa(S_OR(attended_transfer, blind_transfer));
(gdb) p attended_transfer
$1 = 0xb7394b21 ""
(gdb) p blind_transfer
$2 = 0x0
(gdb)
{noformat}

However, if you uncomment the BLINDTRANSFER line then it won't crash.
