Which version of CVS are you using?
By: Steve Hanselman (shanselman) 2004-03-23 11:09:58.000-0600

Just re-updated my cvs tree (5 mins ago), rebuilt, installed and retested, so a bug on the very latest CVS as of this entry.
By: Olle Johansson (oej) 2004-03-23 11:43:30.000-0600

Happens for me on Linux, but not on Freebsd.
Asterisk does not crash, but the remote CLI (asterisk -r) crashes.

Asterisk -c doesn't crash.
By: Steve Hanselman (shanselman) 2004-03-23 12:09:48.000-0600

Sorry, this is asterisk -r.
It crashes the remote console not asterisk.
By: slepp (slepp) 2004-03-23 14:19:18.000-0600

I can't reproduce this error in either one.

Took me a few minutes to see why it happened on one box but not the other.  It's all about the number of applications.  The buffer is too small.  Fixing it up right now.  I'll close this out once I get it fixed
By: James Golovich (jamesgolovich) 2004-03-24 03:14:22.000-0600

Fixed in CVS (HEAD and stable)
