[erlang-questions] cover.erl issues

[Manuel A. Rubio "Bombadil"]

Hi!

I was developing a lot of projects with rebar and, when I put only one 
app in the apps directory and use eunit and cover, it works well, but 
when I create several apps in this directory I often see this message:

-----------------------------------------------------------------------------------------
ERROR: eunit failed while processing 
/home/manuel/Proyectos/myproject/apps/app2: {'EXIT',
     {{badmatch,
          {error,
              {badarg,
                  [{ets,new,
                       [cover_internal_data_table,
                        
[set,public,named_table,{write_concurrency,true}]],
                       []},
                   
{cover,init_main,1,[{file,"cover.erl"},{line,565}]}]}}},
      
[{rebar_eunit,cover_init,2,[{file,"src/rebar_eunit.erl"},{line,445}]},
       
{rebar_eunit,run_eunit,3,[{file,"src/rebar_eunit.erl"},{line,127}]},
       
{rebar_core,run_modules,4,[{file,"src/rebar_core.erl"},{line,405}]},
       {rebar_core,execute,5,[{file,"src/rebar_core.erl"},{line,334}]},
       
{rebar_core,process_dir1,6,[{file,"src/rebar_core.erl"},{line,197}]},
       
{rebar_core,process_each,5,[{file,"src/rebar_core.erl"},{line,268}]},
       
{rebar_core,process_dir1,6,[{file,"src/rebar_core.erl"},{line,173}]},
       {rebar_core,process_commands,2,
           [{file,"src/rebar_core.erl"},{line,61}]}]}}
-----------------------------------------------------------------------------------------

I think that can be due to a race condition, because the eunit 
execution between apps is continuous... but I'm not sure :-/

Any idea?

Thanks.
