           Summary: ICE (illegal instruction) with static foreach over
                    empty member template
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: ice
          Severity: normal
          Priority: P1

//////////////// test.d ///////////////
struct S
{
    template tpl()
    {
    }

    void fun()
    {
        static foreach (p; this.tpl!())
        {
        }
    }
}
///////////////////////////////////////

Compilation fails with:

be = '.' this.tpl!() at [test.d(9)]
[1]    3724069 illegal hardware instruction (core dumped)  dmd -o- test.d

For whatever reason, the "this." is important.
