As we are still in the process of getting our tools in shape: we would first
like to confirm that our tools are able to diagnose known bugs; we will then
continue to look for not yet identified issues on your code. At present we have
to rely on our own examples (and's maintenance worsens this...).

Thank you very much for the pointer, we'll take a look at this database. The
main hope associated with my prior email was that someone would know of such
issues off the top of their head. If anybody does: please let us know.
