Dialyzer version v2.2.0 From Erlang 13B04 failure

Hello All:





I have been very keen to try the new distribution and was in particular
looking forward to the new dialyzer version that has parameterized
support (so that we can check our code with it). I get the errors
attached at the end of this e-mail (I show the plt file construction for completeness, the error happens in the actual dialyzer analysis), any ideas about what is happening
and how I can help to fix it (help in creating a simple test case would be appreciated).




Thanks:





Bill M.
