Test case (scan16.ii)
That's a new regression. It was working when I reduce PR63813 (i.e. on
2014-11-11) as that ICE came later. It now ICEs with todays GCC (r217759).
g++ -S -std=c++11 -fsanitize=undefined scan16.ii
scan16.ii:51:28: in constexpr expansion of
‘std::validator.std::unique_ptr<std::Validator>::unique_ptr()’
scan16.ii:51:28: internal compiler error: Segmentation fault
unique_ptr < Validator > validator;
