Summary:                    [patch] channel_find_locked causes loops (e.g. in
handle_chanlist)
Description: 
Hi,
an error in channel_find_locked causes asterisk to loop under certain
circumstances. This happens when the function retries to find a channel
because it was locked. The prev-reference is already overwritten (NULL)
when the function walks through the list again. So the first element
matches and the whole thing (i.e. the using function) might start to loop.

Patches:
      asterisk-1.4.9-channel.c.patch uploaded by fnordian (license 110)
Restore previous behavior where if we failed to lock the channel we wanted
we would return to exactly the same point as if we had just reentered the
function.
