Comment (by ckb):

 The majority of these appear to be false positives. I fixed
 http://git.bind10.isc.org/~tester/builder/BIND10-clang-static-
 analyzer/20130125080342-MacOS/logs/files/scan-build/2013-01-25-1/report-
 153A8p.html#EndPath
 and
 http://git.bind10.isc.org/~tester/builder/BIND10-clang-static-
 analyzer/20130125080342-MacOS/logs/files/scan-build/2013-01-25-1/report-
 2TcSQs.html#EndPath
 in branch trac2665

 the one in http://git.bind10.isc.org/~tester/builder/BIND10-clang-static-
 analyzer/20130125080342-MacOS/logs/files/scan-build/2013-01-25-1/report-
 TaAeBU.html#EndPath
 appears to be intentional, and I am not sure how it could be done more
 efficiently.
