Модульное тестирование в erlang

Никто не сталкивался с такой ошибкой при использовании eUnit в erlang?

{eunit_proc,buffer_to_binary,1,
    [{file,"eunit_proc.erl"},{line,276}]},
{eunit_proc,group_leader_loop,3,
    [{file,"eunit_proc.erl"},{line,600}]}]}

eunit_proc.erl https://github.com/erlang/otp/blob/maint/lib/eunit/src/eunit_proc.erl#L276
