[sv-ec] The behavior of randomize with arguments

I'd just like to confirm the behavior of a class randomize call that has
arguments, described in LRM 13.10.  In the example below, will the
randomize method call return 0, indicating failure?  And this is because
constraint c2 cannot be true?

Thanks,
Bill Paulsen

class class1;
  rand int a,b;
  constraint c1 { a >= 20 && a <= 30; }
  constraint c2 { b >= 50 && b <= 60; }
endclass
...
class1 class1_h = new;
...
class1_h.b = 0;
result = class1_h.randomize(a);
