It's just a bug in libgcj :-(.  You can reproduce it with the
appended.  How odd that we've never run across this before.

_Jv_CheckArrayStore needs to be taught about multi-dimensional arrays.

class a
{
}

class b extends a
{
}

public class ar
{
  public static void main(String[] args)
  {
    a[][] x1 = new a[3][3];
    b[] x2 = new b[5];
    x1[0] = x2;
  }
}
