Description Alex Rønne Petersen 2012-01-19 09:13:51 UTC 
This builds:

enum Test : ubyte
{
    foo,
    bar,
    baz,
}

void main()
{
    auto i = Test.bar;

    final switch (i)
    {
        case Test.foo:
            break;
    }
}

Remove the : ubyte and it doesn't.
Comment 1 Alex Rønne Petersen 2012-01-19 09:17:28 UTC 
Andrej Mitrovic notes that if : int is specified as the backing type, the sample fails to build as expected. So, it seems as if any non-default backing type causes the bug.
