Summary:                    asterisk use 99% cpu when agi script uses
$AGI->exec("Dial","Local/ext at extensions")
Description: 
We have agi scrips that redirects calls using
$AGI->exec("Dial","Local/100 at extensions")

But it seems there may be a problem on chan_local.c

I am attaching the gdb and locks output.
