scan-build: Removing directory
'/var/folders/p6/r86f0tb17tq2c5crbndb0q7m0000gn/T/scan-build-2012-01-24-1'
because it contains no reports.


I can fix this using a solution listed here:
http://stackoverflow.com/questions/7820011/clang-scan-build-wont-work-with-xcode-4-2-llvm-3-0-build-configuration
however even when using this "hack" the results imply the scanner does not
recognise ARC'd code as I have numerous false warnings about potential memory
leaks.

Thanks for any help
