Richard S. Hall closed FELIX-978.
---------------------------------

    Resolution: Fixed

I have committed a patch to address this issue, so I will close it. I have also added a test
case to the BND testing harness in my sandbox to check for this situation in the future.

> When the resolver is calculating the set of potential candidates for module being resolved,
it uses a map to store the potential candidates associated with each module that needs to
be resolved. It also uses this map to detect cycles. In the case there are no potential candidates
to resolve a dependency, the attempt to populate candidates for the given module fails. However,
the failed module is not removed from the candidates map. The result is in certain situations,
the resolver may end up wiring to the failed module since it still has candidates in the candidate
map. This typically can only happen if there are multiple dependencies on the failed module
with at least one of them being optional.
