This doesn't appear to be a problem on Win32.

----------

module a;

private
{
    struct IsEqual( T )
    {
        bool opCall( T p1, T p2 )
        {
            return p1 == p2;
        }
    }    

     template ElemTypeOf( T )
    {
        alias typeof(T[0]) ElemTypeOf;
    }
}

template find_( Elem, Pred = IsEqual!(Elem) )
{    
    size_t fn( Elem[] buf, Elem pat, Pred pred = Pred.init )
    {
        return buf.length;
    }
}

template find( Buf, Pat )
{
    size_t find( Buf buf, Pat pat )
    {
        return find_!(ElemTypeOf!(Buf)).fn( buf, pat );
    }
}

----------

module b;

private import a;

int fn()
{
    return find( "123", '2' );
}

----------

Simply run "dmd a.d b.d" and watch the fireworks.  This appears to be related
to the default final parameter, Pred.
