Description:Although incoming SIP and IAX2 channels work, all attempts to use the Dial command to create SIP, IAX2, or Local channels fail as follows:

I did some googling and discovered this:

http://www.asteriskguru.com/archives/svn-commits-russell-branch-russell-jack-r95440-team-ru-vt117085.html

Made the change near line 3437 and things seem to be running so far.  Seems ungood to ignore a failure to lock, though.

This problem persists in the latest SVN:

Asterisk SVN-branch-1.6.0-r152772-/trunk built by root @ jrcovert.covert.org on a Power Macintosh running Darwin on 2008-10-30 16:39:33 UTC

without ignoring the failure to get the lock (seems like a bad thing to ignore) it's not possible to run on Darwin.

This problem persists in 1.6.0.3.

I'm including a patch which does the "hack" russell used above, but it seems like the real cause for failing to lock should be found.

After much testing, I figured it out.  The problem was in how rwlocks were initialized.  Patch uploaded, which works on my system, which is a PowerPC G4 running OS X 10.4.6.
By: John Covert (jcovert) 2009-01-21 17:48:04.000-0600

Thank you.  I've put it up on two systems, a PowerPC G4 laptop running 10.4.11 and a PowerPC G5 also running 10.4.11.  Seems to work good, lasts a long time.

AST_RWLOCK_INIT_VALUE is always defined.  What we really wanted to ask is
whether autoconf detected a static initializer value.  This fixes rwlocks
on all such platforms (mainly, Mac OS X).
