Summary:                    Asterisk res_odbc causes SEGFAULT's if unable to
connect to server.
Description: 
I have res_odbc.conf configured with both a local and remote DSN.  If
connectivity is lost to the either the local remote DSN, Asterisk
SEGFAULT's.

Was seeing this issue intermittently, but when I place an IPTABLES rule to
block outbound ODBC connections to the remote DSN or disable the local
MySQL server, Asterisk will crash each time I start it up.

I also only tested with the local MySQL DSN listed in res_odbc.conf and
odbc.ini and still had the same crashed with the local MySQL turned off.

A related bug is that it seems sometimes Asterisk loses contact with the
local MySQL connection (via /var/lib/mysql/mysql.sock) and that also
triggers this connection crash.

Desired outcome is that Asterisk should continue to run and periodically
attempt reconnects.

CentOS 5.6 x86_64
Asterisk 1.6.2.18
MySQL 5.5.11
MySQL ODBC Connector 5.1.8

Full BT's attached.
