[erlang-questions] R12B-1 dialyzer 'Unsupported primop' error

In R12B-1 the following seemingly correct (if not so useful) program  
yields the error {'Unsupported primop', bs_context_to_binary} when  
dialyzer runs with the "Old Style" analysis option.

     -module(test).
     -compile(export_all).
     start(<<>>) -> ok.

The compiler seems to emit the primop when the function arguments  
contain a binary match and there is no final catch-all clause. My code  
runs as expected so I am assuming  this is a dialyzer issue?
