Summary:                    System completely hangs after executing an ODBC
function
Description: 
Currently I am working to upgrade asterisk 1.4.21 to 1.4.27. During testing
of my dialplan I discovered that the system will completely hangs after
executing an ODBC query in the h extension. The CLI shows no verbosity and
debug messages. Also the SSH connection is dropped and no new SSH
connection can be made. The only reaction of the system is a ping reply.
The system has to be turned off and on to make the system work again!!

This problem is introduced in asterisk 1.4.22. However, I cannot find out
which change causes this problem. I have searched in the changelog for a
possible cause, but I cannot find out.

Below you can find the steps to reproduce. When the dialplan executes the
odbc query in the h extension, the whole system hangs.

---------------------------------------------------------------------- 
A small update: I've discovered that the crash only occurs when the calling
party hangs up. When the called party hangs up, the ODBC function will be
executed without any problem.
