+%%%
+%%% A module with an erroneous record field declaration which mixes up
+%%% structured and opaque terms and causes a crash in dialyzer.
+%%%
+%%% In addition, it revealed that the compiler produced extraneous
+%%% warnings about unused record definitions when in fact they are
+%%% needed for type declarations. This is now fixed.
