I am getting this error when I am instantiating a struct array with a
single element inside another class and only if there is the
destructor for the struct is explicitly defined. Is it a known error?

Here is a minimized snippet that gives error:

$ rdmd --main -unittest test.d
Error: this for ~this needs to be type foo not type foo[1u][1u]
Error: this for ~this needs to be type foo not type foo[1u]


// test.d

struct foo {
  int foofoo;
  ~this() {                     // no error if explicit destructor not
                                // defined
  }
}

class bar {
  foo fred;
  foo[2][2] foofoo;
  foo[1] frop;                  // this gives error
  foo[1][1] fropfrop;           // this too
}

unittest {
  foo frop;
  foo[1][1] fropfrop;           // this works
  bar burp;
}

I think it is a bug.  The compiler appears to be "optimizing" out the  
array, since you are creating a static array of exactly one element, it's  
the same as just creating an element.

But it somehow forgets that it optimized that out.

Please file on bugzilla.
