Summary:                    crashes with "*** glibc detected *** corrupted
double-linked list" with connections to asterisk manager
Description: 
I'm running asterisk 1.4.x with a IAX uplink and some SIP phones.
Essentially, this works fine. However, when making connections to the
asterisk manager interface [from a php application, in a certain timed
fashion], asterisk crashes while showing a notice like:
*** glibc detected *** corrupted double-linked list: 0x081cb7e0 ***
This happens reproducibly on three different boxes, all with different
hardware.

I haven't seen any crashes before we started using the manager interface,
in over four weeks of development on three machines. The thing that is
really bothering me is that actually stressing the server prevents creahes
as well. In other words, when I run this script in a 'while [ 1 ]' loop
from bash, then there are no crashes:

#!/bin/bash

function text2() {
cat <<- EOF
Action: Login
UserName: webtool
Secret: demo

EOF
}
function text3() {
cat <<- EOF
Action: Command
Command: show channels

EOF
}
function text4() {
cat <<- EOF
Action: Logoff

EOF
}
(text2 ; text3 ; text4 ; sleep 0.1) | telnet 127.0.0.1 5038
