Unfortunately the checker still has a large number of false reports. Some of these are due to oddities in gdb -- cleanups mostly -- but some are bugs in the checker itself. I've filed bug reports against the checker (and fixed some bugs as well); and will file more later. I built and regtested this series on x86-64 Fedora 18. I think most of the patches are pretty obvious. I intend to run the checker periodically and fix problems. I don't think we can reasonably require it for changes in the Python code, due to all the false reports :-( Tom
