When the following is compiled with

Sqlite.d:
----
module Sqlite;

class Result(T)
{
    T[] mResults;
//import tango.util.log.Trace;
import tango.util.log.Log;

    {
        return mResults.length;
    }
}

dmd compiles without error, when it should complain about the unterminated documentation comment in Log.d. In LDC this leads to some weird semantic errors: http://dsource.org/projects/ldc/ticket/447
