Thanks for your bug report. This is a knonw bug, see
http://gcc.gnu.org/bugs.html . g++ thinks this is going to be a
declaration of a function, expecting an argument of type Scalar, named
r, and a parameter named i, which is implicitly of type int, which is
an error.

To work-around this bug, you can write

  const Set set3((0,Scalar(r)), i);

This will tell the compiler that the hole thing is an expression.
