// Regression test for Issue #33890.
//
// This fails if type literal constants are not deferred, but their RTI
// representation is. This test however will not detect if we accidentally start
// building the RTI representation in the main deferred unit (which is what was
// happening before the bug was introduced).

  print(a.B); // into the main output unit.
