>Description:
An inner class with an empty instance initializer block that
also has an explicit constructor results in an error:

$ gcj -c Empty.java 
Empty.java: In class `Empty$Inner':
Empty.java: In method `Empty$Inner(Empty)':
Empty.java:0: Tree check: expected block, have compound_expr
Empty.java:0: Internal compiler error in fix_constructors, at ./parse.y:8384
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

my line 8384 reads:

	  compound = add_stmt_to_compound (compound, NULL_TREE,
					   BLOCK_EXPR_BODY (main_block));
>How-To-Repeat:
Try to compile this test case:

class Empty
{
  class Inner
  {
    {
    }
    
    Inner() {}
  }
}
