Version:
------------
Erlang R16B01 [source-01eb200],

Steps to reproduce:
-----------------------------
After cloning this repository...

    git clone git://github.com/abhay/eunit.git

and running...

    make

I get a crash from the lint_module:

erlc -pa ../ebin -W -I../include +warn_unused_vars +nowarn_shadow_vars
+warn_unused_import -o../ebin eunit.erl
eunit.erl:none: internal error in lint_module;
crash reason: {function_clause,
               [{erl_lint,expr,
                 [{record_field,
                   [{line,{"eunit.erl",0}}],
                   {atom,[{line,{"eunit.erl",0}}],''},
                   {atom,[{line,{"eunit.erl",0}}],eunit}},
                  [],...

Analysis:
-------------
It is related to the deletion of a clause in erl_lint that was handling
packages:

    erl_lint: Remove support for packages

     {Rvt,St1} = record_expr(Line, Rec, Vt, St0),
     {Fvt,St2} = check_record(Line, Name, St1,

The input module is of course legacy code and should be updated, but I
think a better error message would be nice.

Cheers,
