---------------------------------------------------------------------- 
I initially marked as a NewFeature because
send_provisional_keepalive_full() is a function from a new feature (?) from
the Reviewboard link (https://reviewboard.asterisk.org/r/315/) incorporated
in version 1.4. Just for information, we removed ALL the code regarding the
"Re-send non-100 provisional responses" commit and the crash has stopped.
We had two boxes running with this problem. The other the crash still occur
and it is available to test patches. Thanks.
