--- Comment #4 from Tavian Barnes <tavianator at gmail dot com> --- I meant to include -std=c++11 in the OP, it still happens with that flag set. Good suggestion for the replacement though. The actual code was closer to i < length ? a[i] : throw ... but I guess that can become (i < length ? a : throw ...)[i].
