I'd guess that scan-build will use whatever clang executable it finds
first on your PATH. Perhaps just set your PATH to point to your clang
build before any other, and then try?
Note: I can't verify this, it's just reasonable speculation. Ted or
someone would have to chime in to tell you the truth with any

I've written a few checkers in my spare time too and honestly I
normally end up putting them in the 'Core' package (in Checkers.td)
during development so they are always on by default and I can just use
'scan-build,' and move them to other packages (like core.experimental)
later once I'm done. Granted I only wrote tiny ones that I didn't push
upstream (because coincidentally, other people ended up
re-implementing them within the same day or two. :)
