<br><br>You can post the bug report preferably on the erlang-bugs mailing list<br>
but then you must provide<br>
more detailed info where you point at the actual error in the code or<br>
even provide a patch.<br>
Another option is to provide a minimal program example which shows the<br>
bug when run.<br>
