Zebble - can you find anyone else with the same problems?  I'd like to see if this is effecting everyone, or if it can be narrowed to some change that interacts poorly with just your system.  There were some changes that might have touched lpc10, but it is unclear if they would have changed ilbc.

I just uploaded a change that will fix the warning, without changing what is done in these two spots in iCBSearch.c...  That should take care of the quality issue.
