Summary:                    IMAP segfault under load or multiple vmail users
Description: 
Using commercial version of DRUID based on Asterisk 1.4.22. The system
randomly crashes but experience it under load or increased voicemail usage.
Not getting support from them so asking the larger (and better) Asterisk
crowd.

Crash always happens in libc-client (imap-2004g) where it appears to be
receiving garbage in the IMAP reply. There also are always two threads
involved. Attaching backtrace of three crash incidents and snippet of log
file.

Can recreate this issue on system using pjsua and placing simultaneous
calls to voice mail for different users. 3 users and 5 calls is all it took
to segfault.

Hope someone can shed some light on to what this is. It is totally
unacceptable for a production system environment.
