void seed( result_type value = 0u ); (1) (since C++11)

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
LWG 2181 C++11 overload (2) would not throw even if the seq.generate call throws propagates the exception
