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'm very sorry, but I can't reproduce the crashes when running under
valgrind.

I'm experiencing crashes when asterisk is started as:
/bin/su asterisk -c "/usr/sbin/asterisk -vvvfg"
/bin/su - asterisk ; /usr/sbin/asterisk -vvvfg
/usr/sbin/asterisk -vvvfg
or when started from safe_asterisk as root or as user asterisk.

I'm seeing no crashes when started as:
valgrind /usr/sbin/asterisk -vvvfg
/bin/su - asterisk ; valgrind /usr/sbin/asterisk -vvvfg
/bin/su asterisk -c "valgrind --log-file=/var/lib/asterisk/valgrind.log
/usr/sbin/asterisk -vvvfg 2>/var/lib/asterisk/malloc_debug.log"

I'm not an experienced valgrind user. Is there another way I could run
valgrind that might nog prevent the crashes from happening? Is it useful to
have a memory leak summary or valgrind log file output after running
valgrind for some time but without the crash?

Sorry for the trouble and thanks for all the help so far.
