---

If a dialyzer module attribute references an undefined (local) function an error tuple is thrown but no caught. This leads to a `nocatch` error and not the intended "clean" error:


{code:erlang}
{{nocatch,{error,"  Unknown function undef/0 in line dial.erl:3"}},
 [{dialyzer_utils,check_fa_list1,3,[{file,"dialyzer_utils.erl"},{line,748}]},
  {dialyzer_utils,get_func_suppressions,2,
                  [{file,"dialyzer_utils.erl"},{line,568}]},
  {dialyzer_utils,get_fun_meta_info,3,
                  [{file,"dialyzer_utils.erl"},{line,521}]},
  {dialyzer_analysis_callgraph,compile_common,7,
                               [{file,"dialyzer_analysis_callgraph.erl"},
                                {line,410}]},
  {dialyzer_worker,loop,2,[{file,"dialyzer_worker.erl"},{line,93}]}]}
{code}
