--- Comment #3 from Paul Wankadia <junyer at google dot com> ---
https://github.com/google/re2/issues/102 reported the same error with GCC
6.1.1:

This is the flexible array member:

    std::atomic<State*> next_[];

Is this likely to be the same issue even though std::atomic<T*> should have a
trivial destructor for all T?
