As a preparatory step the inliner maps the inlined body with a tree type map. This map adjusts the tree and at the same time sets up the environment for typing the tree. But this has the potential that re-typing during copying will fail since the environment is not yet set up correctly. We avoid the problem by ignoring a specific failure (function type in application does not exist) and proceeding with the previous type.
