Reported by %u.
------------
struct S
{    
  static int func() {
    S s;
    int e;
    switch( e )
    {  default: return 0;
    }
  }    
  static int[1] ARR = [func() ];
}
----
Assertion failure: '!cases' on line 2741 in file 'statement.c'

abnormal program termination


It's happening because the CTFE for ARR speculatively runs func().
There's a 'no size yet for forward referenced struct' error because S isn't
complete yet. But this happens with errors gagged.
The SwitchStatement completes its semantic pass correctly. 
But, because "S s;" failed, semantic gets run again for func(), without errors
gagged this time. SwitchStatement::semantic() detects it's been run twice, and
asserts.
